How to Plan a Multi-City Trip: The Part Nobody Writes About

There are hundreds of articles about how to plan a multi-city trip. They cover route planning, shoulder season vs. peak season, which cities to pair, how long to spend in each place.

This isn't one of those articles.

This is about what happens after you've decided all of that — when you have a Ryanair booking, two Booking.com hotels, a Trainline confirmation, and a ferry ticket from a Croatian operator, and your trip exists as 11 separate confirmation emails from 7 different providers. That's the part that breaks trips. Not the route. The bookings.

The moment the trip breaks

There's a specific moment in booking a multi-city trip where it goes from manageable to chaotic. It's not the first booking. It's usually around the third or fourth.

You have a flight in. You have the first hotel. You add a train to the second city, and then a hotel there. Then another flight. And now you're not sure whether the train arrives before or after the hotel check-in opens. You're not sure whether there's a night you forgot to account for between the second city and the third. You have four tabs open and you're copy-pasting dates into a Notes document. This is normal. It happens because each booking is siloed — each provider only knows about their own segment. None of them know about each other. None of them can tell you whether your bookings connect.

Why multi-city trips are harder than single-destination

When you book a week in one place, the itinerary is simple: arrive, stay, leave. One flight, one accommodation, done.

A multi-city trip with three destinations involves, at minimum: two or three flights or trains between cities, accommodation in each city, and the connective tissue between each segment — the travel day itself, the time between check-out and check-in, the transfers within cities.

That connective tissue is where the problems live. Different booking platforms don't talk to each other. A Trainline booking doesn't know about your Booking.com check-in time. Your flight confirmation doesn't know that your last hotel check-out is at 10am and your flight home is at 9pm. The only person who can see the whole picture is you — and only if you've somehow assembled all those bookings into a single view.

The three things that go wrong most often

1. An unbooked night.This is the most common error on multi-city trips, and the hardest to catch in your inbox. You arrive late into a city, you're tired, you're focused on the next day's activity — and you booked accommodation for every night except that one. Maybe you assumed you'd be overnight on the train. Maybe you miscounted. Maybe the dates just slipped. An unbooked night in a popular city at short notice is expensive. In high season, it can mean the difference between €80 and €250 for the same quality of room.

2. A tight connection between cities.Not at airports — between cities entirely. The train from Zurich arrives at 18:10. The connecting train to Innsbruck departs at 18:20. You bought those tickets separately, months apart, without checking the connection time. Now you have a 10-minute window in a station you've never been to. This is particularly common with rail bookings, where people often book individual legs without checking the end-to-end sequence.

3. Multi-airport city traps.Several major cities are served by more than one airport. Paris has CDG and Orly. London has Heathrow, Gatwick, Stansted, Luton, and City. Rome has Fiumicino and Ciampino. Milan has Malpensa, Linate, and Bergamo. If you fly into CDG and out of Orly, that's not a short taxi — it's 45 minutes to an hour by bus, depending on traffic. If you haven't noticed that your inbound and outbound flights use different airports, you might not leave yourself enough time to get between them.

What a good itinerary actually looks like

The answer is simple, and it's the only structure that reliably catches the above problems: one timeline, in date order, with every booking on it.

Not a city-by-city list. Not a spreadsheet with separate tabs per destination. One linear view: depart London at 07:30, arrive Barcelona at 10:45, check in to hotel at 15:00 (note: 4-hour gap, check luggage storage). Train to Valencia on Thursday at 09:20, arrive 12:40. Hotel check-in from 14:00. And so on.

When every segment is chronological and in one place, gaps become visible. A missing night is a blank space in the timeline. A tight connection is two events right next to each other. A different-airport departure shows up as a location change you have to navigate. Most travellers build this in a Notes doc or a spreadsheet. It works, but it's manual and easy to get wrong. And it doesn't automatically flag when the check-out time doesn't match the check-in time for the next property.

How to assemble your itinerary from existing bookings

If you already have bookings across multiple providers, here's the process:

1. Go to Travel Sane. No account needed to try it — paste a confirmation and see what comes back.
2. Paste each confirmation email— full text, directly from your inbox. It doesn't matter whether it's from Ryanair, Booking.com, Trainline, Agoda, a hostel, or a ferry operator. Any language, any format.
3. Watch the timeline build — each booking appears in date order on a single timeline.
4. Check the flags — Travel Sane highlights unbooked nights, tight connections, and location mismatches automatically.

You're not re-entering dates or building a spreadsheet. You're pasting what you already have, and the structure appears.

Before you fly: the verification checklist

Once the timeline is built, run through these:

• Accommodation every night — Is there a hotel, hostel, or Airbnb on every date of the trip?
• Connection times — Are there any flagged tight connections? Do the airport MCTs work for your layover?
• Airport terminals— If you're connecting between flights, are they in the same terminal? If not, is the layover long enough?
• Same-city airports — Do your inbound and outbound flights use the same airport?
• Check-in/check-out timing — Does your accommodation open for check-in before you arrive? Do you have somewhere to leave bags if not?
• Visa requirements— For each destination, do you need a visa or entry requirement? This is outside Travel Sane's scope but worth a separate check.

The trip doesn't break where you think it will

Most multi-city trips that go wrong don't fail because the route was bad or the cities weren't right for each other. They fail at the joins — the overnight that got skipped, the connection that was tighter than it looked, the train that arrived at the wrong station. Those are fixable problems, but only if you can see them. The bookings are all there. The information is all there. It just needs to be in one place, in order, with the gaps visible.
