How to plan a trip, step by step

Planning a trip feels like one huge job, which is why people put it off and then book in a panic. It is really a handful of small decisions that depend on each other. Make them in the right order and each one gets easier, because the one before has already narrowed the options.
Here is that order.
1. Decide who is coming
Everything else depends on this. A trip for two can change its mind on the way to the airport; a trip for eight cannot. Settle who is definitely in, who is probably in, and who needs to decide by a certain date. If other people are involved, have the budget conversation now, not after the flights are booked. There is more on that in planning a trip together.
2. Pick the dates, or the window
Most people do not have a free choice of dates. Work out the earliest you can leave and the latest you must be back, then ask how much of that window you actually want to use. A trip that fills every available day tends to be tiring; one with a spare day at each end is calmer.
Check three things against your window: school and public holidays at home, the season at the destination, and any event that fills the place up or closes it down. Weather and crowds change more than people expect from one month to the next.
3. Choose the destination
If you already know where you are going, skip ahead. If you do not, pick by what you want from the trip rather than by a name. Do you want to walk, eat, swim, do nothing, or see a lot? Then match that to places that are good at it in your window. The country guides on this blog each cover when to go and where to go, which is a quick way to compare.
Say no to some places. A short list of two or three is easier to compare than twenty.
4. Set a rough budget
You do not need a spreadsheet yet, only a ceiling and a feeling for where the money goes. Most trips come down to four buckets: getting there, where you sleep, food, and things you pay to do. Getting there and sleeping are usually the largest and the earliest to book, so decide those first and see what is left for the rest.
Add a small cushion for what you cannot predict. It is nearly always used.
5. Book the big pieces
Transport to the destination and somewhere to sleep come first, because they limit everything else and they are the things most likely to run out or rise. If you are unsure how early is early, how far in advance to book goes through it by type of booking.
A sensible habit: where a booking can be cancelled or changed, book it sooner and keep your options open; where it cannot, wait until you are sure.
6. Sketch the days
Now you can make a rough shape. Give each day a purpose, not a timetable: arrival, a big sight, a slow day, a day trip. Leave gaps. The common mistake is to plan every hour, and then feel behind by lunchtime on day one.
Keep a separate list of ideas that have not been given a day. Moving them onto a day later is easier than deleting them from one.

7. Check the gaps
Go through the trip day by day and ask three questions of each one: how do we get there, where do we sleep, and is there anything planned at all? A night with no bed or a transfer with no ticket is the usual surprise. Finding them a month ahead is an inconvenience; finding them on the day is a problem.
8. Sort the paperwork and the practical bits
This is the stage people leave too late. Check that passports are valid for the trip, find out whether the destination needs a visa or an entry authorisation, and look at travel insurance. The rules differ by country and change, so always check the official government site of the place you are visiting and your own government's travel advice, not a forum post.
Then the smaller things: how you will pay, how you will get a phone signal, whether you need a plug adapter, and whether anyone has medication that needs special handling.
9. Share the plan
A plan only one person can see is a plan one person has to answer questions about. Put the confirmations with the itinerary, share it with whoever is coming, and make sure it can be opened without a connection. A confirmation buried in an inbox is no use at a station with no signal.
10. Pack and go
Pack from the plan rather than from habit: the weather, the activities, and what you are carrying between places. A packing list that knows where you are going saves doubling up on things like adapters and first-aid kits.
The week before you leave, reread the plan once, top to bottom. You will catch the thing that does not add up.
Keep it moving
The order above is a guide, not a law. You may know the destination before the dates, or the budget before the group. What matters is that each decision gets made once, written down, and visible to everyone it affects. Start with who and when, and the rest of the trip will follow.
