The complete guide to planning any trip from scratch — Budge

A practical end-to-end guide to planning any trip: destination, budget, dates, booking sequence, itinerary, visas, packing, and when to stop researching and just go.

Most people plan trips in the wrong order. They pick a destination, spend three weeks reading blog posts and saving Instagram locations, build an itinerary that's far too ambitious, book flights at 11pm on a Tuesday, then panic-book accommodation two weeks before departure when half the good options have gone. The trip usually turns out fine — humans are adaptable — but there's a better sequence, and it makes the whole process faster, cheaper, and less stressful.

This guide is that sequence. Every phase of planning a trip, in the order that actually makes sense, with honest takes on where most people waste time and where they don't spend nearly enough.

It's written to work for any trip: a first visit to Japan, a two-week road trip, a city break, a long-haul adventure. The principles are the same even when the specifics change. Where a destination example helps, you'll find one — if you're using Japan as your case study for this process, the destination-specific detail is all there.

Phase 1: Choosing a destination (and actually committing to one)

The decision you're really making at this stage is not "where should I go" — it's "what do I want from this trip."

These are different questions and conflating them is the source of most planning paralysis. "Where should I go" has infinite answers. "What do I want from this trip" narrows the field fast: Do you want novelty or comfort? Challenge or rest? Culture or nature? To travel solo or with a group? Two weeks of deep immersion in one place or a faster survey of several?

Answer those questions first and the destination choice largely makes itself.

A practical approach: write down three or four candidate destinations and force a decision by the end of a single session. For each one, ask: what would I actually do there, how much does it cost to get there, and do I have the time and budget for the version of this trip I actually want? One of these questions will usually eliminate at least two candidates without much further analysis.

The trap to avoid at this stage is the comparison spiral — spending three weeks reading "Tokyo vs Kyoto" forum threads when the real question is whether Japan is the right destination at all. Pick the destination, commit to it in writing (book something non-refundable if you need to force the decision), and move to the next phase.

A few destination-level questions worth asking before you commit:

Is this the right trip for who's travelling? A solo trip and a trip with a partner who has different interests and a trip with children are fundamentally different planning problems. The destination that's ideal for one configuration may be actively difficult for another. Japan is excellent for solo travel and for couples, but the long international flights, the all-day walking, and the high-stimulus city environments are genuinely hard with young children in a way that some destinations aren't. Think about who's coming and whether the destination works for the way that group actually travels.

Does the trip I want actually exist there? People often fall in love with a version of a destination constructed from photographs and travel content that tends to show the best light, the least crowded moments, and the parts of a place that photograph well. The actual experience may be excellent and quite different. A quick search for honest, unfiltered accounts — Reddit forums for the destination, recent reviews from people with similar interests — does more useful calibration work than any number of professionally produced travel guides.

Have I considered the obvious alternative? If you're drawn to Japan for the temples, old streets, and food culture, have you considered Taiwan? Vietnam? Portugal, if the long haul is a constraint? Comparing your shortlisted destination against its nearest alternative is a useful forcing function — it either confirms you want the specific thing only that destination offers, or surfaces that something closer and cheaper might suit you just as well.

Phase 2: Setting a real budget

Set the budget before you do any detailed research — not after. Researching a trip without a budget is the fastest way to either overspend or under-plan.

A trip budget has five components, and most people only plan three of them:

Flights. Usually the biggest single cost for long-haul travel, and the most variable. For a rough budget at this stage, use Google Flights' price calendar to get a ballpark for your dates and route. Don't book yet — that comes later — but know the range.

Accommodation. Price per night multiplied by number of nights, with a realistic per-night figure rather than the cheapest option you can theoretically find. If you'd normally stay in a comfortable mid-range hotel, budget for that. You won't be happy in a budget hostel if that's not how you travel, and pretending otherwise at the budgeting stage just creates a shortfall you'll fill with stress later.

In-destination costs. Food, local transport, activities, entrance fees. This varies enormously by destination — a day in Tokyo and a day in Lisbon have almost nothing in common cost-wise. Do a rough per-day estimate using the destination's actual price level. For most Western European cities, ¥€80–€100 per person per day covers comfortable eating and getting around. For Japan, around ¥10,000–¥12,000 (roughly €65–€80) covers a similar level. For Southeast Asia, substantially less.

The two categories people forget:

Visa and admin costs. Some visas cost nothing; some cost £115 (UK to Australia as of 2025, Electronic Travel Authority). Travel insurance runs roughly 4–6% of your total trip cost for comprehensive cover. These are not optional budget lines.

A contingency buffer. Ten percent of your total trip budget, held back. You will spend it. On the flight home upgrade when you're exhausted, on the unexpectedly good restaurant you walk past, on the thing that breaks or the transport strike that forces a taxi. Budget for human behaviour, not ideal behaviour.

Phase 3: Deciding your travel dates

Pick your dates around three factors in this order: your own availability, the destination's seasonal logic, and price.

Most people reverse this — they look for cheap flights first and then try to build a trip around whatever dates come up. The result is a good deal on flights to a destination at its least interesting or most crowded time of year.

The destination's seasonal logic matters more than most planning guides acknowledge. Japan in cherry blossom season is a genuinely different trip from Japan in November — not better or worse, but substantially different in terms of crowds, cost, booking difficulty, and what's available. Kyoto in August is hot and humid in a way that affects how much time you want to spend walking between temples. Lisbon in July is 35 degrees and full of people with the same idea you had.

Research the destination's high, shoulder, and low seasons, and make a deliberate choice about which tradeoffs you're willing to make. Shoulder season is almost always the answer for a first visit to anywhere popular: better weather than low season, fewer crowds and lower prices than high season.

On duration: the instinct is always to go for as long as possible, but longer is not always better. A ten-day trip where you're present and unhurried is better than a fourteen-day trip where you're covering ground compulsively. Think about how you actually travel — how many days before you start to feel the pull of home, or how many days of daily novelty you can absorb before it starts to feel like work — and plan to that.

There's also a practical consideration that most people underweight: the days on either side of the trip. If you have a demanding job and you're flying back on a Sunday night to be at a desk by Monday morning, you will spend the last two days of your trip not really on holiday — you'll be managing the re-entry anxiety rather than being where you are. Build in at least one recovery day after long-haul travel if your life allows for it. The trip that ends on Saturday and leaves you Sunday at home to decompress is a materially better experience than the same itinerary ending on Sunday with a Monday 9am meeting waiting.

Not always possible. But worth planning for when it is.

Phase 4: Research — what to look up and when to stop

Research has two distinct phases: pre-commitment research (is this the right trip?) and planning research (how do I actually do this trip?). Most people skip the first and over-invest in the second.

Pre-commitment research is the quick version: what are the must-know things about this destination that might change whether or how I want to go? Visa requirements. Entry restrictions. Safety considerations. Whether your travel dates coincide with local public holidays that close attractions or spike prices. Whether the thing you most want to do is actually accessible when you're there. Twenty minutes of this saves the particular misery of arriving somewhere and discovering the main attraction has been closed for renovation for six months.

Planning research is the longer process: building out the itinerary, choosing accommodation areas, understanding local transport, finding places to eat. This is where most people spend their time — and where the diminishing returns set in fastest.

There's a real phenomenon in travel planning where the more you research, the harder the decisions become rather than easier. You've read seventeen reviews of two similar hotels and you're more uncertain than when you started. You've built an itinerary and then read a forum post suggesting a completely different approach and now you're not sure about any of it.

This is exactly the kind of research rabbit hole that Budge was built for — you can ask it follow-up questions about any of this and it remembers what you care about across the whole conversation. Instead of holding seventeen open tabs in working memory, you can have a conversation: here's what I'm planning, here's what I care about, what am I missing and what should I reconsider? That's a different mode of research, and it's faster.

For the planning research phase, here's what actually needs to be decided before booking:

The geographic shape of the trip — which areas you'll base yourself in and how you'll move between them. The accommodation type and area for each location (you don't need to pick the specific hotel yet, but you need to know which neighbourhood). The two or three things per location that you'd genuinely regret missing. Everything else can be figured out on the ground.

On where AI fits into this process: it's most useful here, in the research phase, for synthesising information and reasoning through tradeoffs. It's less reliable for specific recommendations that depend on current, local knowledge.

Phase 5: The booking sequence

Book in this order: flights, then accommodation. Never the other way around.

This sounds obvious and yet a surprising number of people book a nice hotel and then discover the flight dates they need are either fully booked or three times the price they'd assumed.

Flights first. Use Google Flights for research — the price calendar view and the "Explore" feature for flexible dates. Book directly with the airline or through a reputable OTA once you've found the flight you want. For long-haul, booking 6–8 weeks ahead tends to hit the window where availability is still good and prices haven't spiked. For peak season travel to popular destinations, earlier is better — 3–4 months ahead for cherry blossom Japan, Christmas Europe, or similar.

Read the full guide to booking cheap flights for the specifics: the days of week that tend to be cheaper, how flexible dates affect price, when budget carriers are actually worth it and when they're a false economy.

Accommodation second. The sequence within accommodation booking matters too. Book the first night immediately after booking flights — even if you change everything else, arriving somewhere new without knowing where you're sleeping is an avoidable stress. Book any accommodation that has constrained supply next: popular ryokan, small boutique hotels with few rooms, anything in a peak season destination. Leave the flexible, easy-to-book accommodation for later.

The booking confirmation email is when a trip becomes real. Save every confirmation somewhere accessible offline — not just in your inbox. A screenshot in your camera roll, or a PDF in a folder on your phone, means you can access it when you're standing in a foreign airport with no data signal wondering what hotel you booked.

Visas and pre-trip admin third. This goes here in the sequence, after flights are confirmed, because visa applications typically require confirmed travel dates. Check visa requirements for every country in your itinerary via your own government's travel advisory site — not a third-party blog, which may be out of date. Note the processing time (some e-visas are instant; some require 8–10 weeks) and apply early. If you need travel insurance, buy it now, while the trip cost is confirmed and before anything can go wrong.

Pre-bookable experiences last. Some things need to be booked months in advance — the Ghibli Museum in Tokyo, the Uffizi in Florence without queuing two hours, certain restaurant tasting menus. Research whether any of the specific things on your itinerary fall into this category, then book them now. Everything else can wait.

Phase 6: Building an itinerary that works

Build your itinerary around days, not sites. The question is not "what can we fit in" but "what does a good day here look like."

The itinerary mistake almost everyone makes is building a list of sites and then connecting them into a day, rather than building a day and fitting sites into it. The difference sounds subtle but produces completely different outcomes in practice.

A list-built itinerary for Kyoto might look like: Fushimi Inari, Arashiyama bamboo grove, Kinkaku-ji, Gion walk, dinner in Pontocho. A day-built itinerary looks like: early morning at Fushimi Inari before crowds, slow walk back down, breakfast near the base, Arashiyama mid-morning, long lunch, Gion in the evening when the light is better and the crowds have thinned. The first version has more items. The second version has a day you'll actually enjoy.

Practical principles:

Cluster geographically. Things near each other go on the same day. This sounds obvious but gets ignored constantly. Moving between different parts of an unfamiliar city takes longer than you think, especially when you're new to the transport system.

Put the high-energy things in the morning. The famous sites, the things that require focus or navigation. Leave the afternoons for wandering, eating, accidental discovery.

Don't schedule dinner. Or rather, don't book dinner in advance unless it's a specific occasion or a restaurant that requires it. Some of the best meals on any trip are the ones you find by walking past the right place at the right time. Locking yourself into a dinner reservation three weeks in advance trades that serendipity for a marginal increase in certainty.

Build in at least one entirely unscheduled half-day per week. This sounds wasteful until you've experienced what happens when you don't: the mounting resentment of having to move on from something you're enjoying, the inability to say yes to anything unexpected because you're already behind schedule.

Calibrate to how you actually travel, not how you think you travel. There's a version of yourself that wakes at 6am and powers through eight hours of sightseeing followed by a long dinner and a nightcap. Most people are not that person by day four of a holiday. Think about your real daily energy arc — when you're sharpest, how many consecutive days of intensity you can handle before needing a slow morning — and plan to that reality. The best itinerary is one that matches your actual travel style, not an aspirational version of it.

Day trips are usually worth fewer of them than you've planned. The romantic idea of a day trip is a three-hour train to somewhere beautiful, three hours of wandering, three hours back. The reality is two hours each way on a good day, compressed time at the destination, and arriving back at your hotel at 9pm tired rather than energised. One well-chosen day trip per destination is usually better than three. Pick the one you'd genuinely regret missing — Nikko from Tokyo, Nara from Osaka, the Cinque Terre from Genoa — and be honest about whether the others are worth the transit overhead.

Leave decisions about the second half of the trip loosely held. The things you want to do on day eight often change once you've actually been somewhere for a week. You discover a neighbourhood you want to return to. You find that a full day at a museum sounds appealing in a way it didn't in the planning phase. You're more tired than expected and want a slow afternoon instead of another temple. Build the second half of any longer trip with some flexibility — confirmed accommodation, loosely held activities — so you can respond to how you're actually feeling rather than what a spreadsheet decided three weeks ago.

The travel planning checklist that accompanies this guide has the full day-by-day structure broken down — it's the practical companion to what's covered here.

Phase 7: Visas, travel insurance, and the admin that people skip

The admin phase is boring and non-negotiable. Do it before you do anything else fun about the trip.

Visas first, covered above. But a few specifics worth knowing:

Visa requirements are passport-dependent, not nationality-dependent in all cases. If you hold multiple passports, check which one gets you better access for your destination. This isn't theoretical — some passport combinations have significant differences in visa-on-arrival rights.

Travel insurance: the single biggest planning mistake people make is buying the cheapest policy without reading what it covers. The things that matter most are medical evacuation cover (should be at least $500,000 for long-haul travel, higher for remote destinations), trip cancellation cover (read the definitions of what counts as a valid reason), and whether adventure activities are included if you're planning any. "Comprehensive" in the name does not mean comprehensive in the policy.

Other admin that's worth doing now:

Check your passport has at least six months of validity beyond your return date — many countries require this and airlines may refuse to board you without it.

Notify your bank that you'll be travelling, or check that your card doesn't charge foreign transaction fees. The Wise card or a Starling account (UK) are worth getting for international use.

Download offline maps for your destination. Google Maps offline download works well; Maps.me is a solid alternative. Do this before you leave, on wifi.

Phase 8: Packing

Pack once, edit twice, and always take less than you think you need.

There are two schools of packing philosophy and I'll tell you which one I've landed on: carry-on only for anything up to three weeks, checked bag for longer trips or trips with specific gear requirements (skiing, diving, extended hiking). The freedom of not waiting at baggage reclaim and not risking lost luggage is worth slightly more constraint on what you bring.

The practical approach: lay everything out, then remove a third of it. Clothes in particular. You will wear less variety than you pack, you can launder things in most destinations, and the weight and space add up fast.

The things people consistently forget: a physical copy of your travel insurance policy and emergency contact numbers (not just in your phone), a small first aid kit with the basics (Imodium, antihistamine, blister plasters — these are the things you'll need and won't want to spend an hour finding in a pharmacy in a foreign language), and something to read on the plane that isn't on a device that might die.

The things people consistently over-pack: "just in case" outfits, full-sized toiletries, more shoes than their itinerary justifies.

On shoes specifically: most people pack three pairs (walking shoes, sandals, something smarter) and wear two of them. The third pair is dead weight. Be honest about which two you'll actually wear given what you've planned, and leave the third at home.

One packing principle that sounds extreme but works: once you've made your final list, go through it again and ask "what would I do if I didn't have this?" For anything where the honest answer is "I'd manage fine or buy it if I really needed it," you have your answer. Replacement toiletries are available in every country on earth. The backup cardigan probably stays in the bag. The specific first aid items and your power adaptor are genuinely worth having.

Phase 9: The final week

The week before departure is for confirming, not planning. Everything should already be decided.

In the final week: confirm all bookings, download offline maps and any apps you'll need, check in for your flight as soon as it opens (usually 24 hours before), and stop reading new trip planning content.

That last one is not a joke. The impulse to read one more blog post, check one more forum thread, find one more restaurant recommendation continues right up until the day of departure for a lot of people. At some point — and the final week is past that point — new information makes the trip worse, not better. It adds noise, introduces second thoughts about decisions you've already made, and creates cognitive load that should be clearing.

The goal in the final week is to reduce mental overhead, not add to it.

The honest truth about planning paralysis

There's a type of traveller — and you may be one, which is fine — who is genuinely better at planning trips than taking them. The planning is satisfying in a way that's hard to articulate: the problem is bounded, the information is findable, the options are theoretically infinite. The actual trip is less controllable, which is both what makes it good and what makes it harder to commit to.

Planning paralysis — the state of researching endlessly without booking — is extremely common, and most travel content makes it worse rather than better. Every new blog post, every Reddit thread, every "hidden gem" listicle adds to the pile of things you haven't yet decided about. The pile grows. The booking doesn't happen.

Here is a concrete heuristic for when to stop researching and just book: you're ready to book when you know the answers to these five questions. Where are you going? When are you travelling and for how long? What's the shape of your budget? What are the two or three things you're most looking forward to? Where are you sleeping on the first night?

If you can answer those five questions, you have enough to book flights and a first night's accommodation. Everything else — the detailed itinerary, the restaurant list, the day trips — can be figured out after the tickets are in your inbox. In fact it's usually easier to research the details once the big decisions are locked, because the constraints are real rather than hypothetical.

The trip you book imperfectly is infinitely better than the perfect trip you never book.

I've planned dozens of trips and the universal truth is that the things I worried about in the planning phase almost never became the problems on the ground. The problems on the ground were always things I hadn't thought to worry about — and I dealt with them, because that's what travel is. The planning gives you a foundation. The rest is just showing up.

Book the flight.
