Nobody starts planning a solo trip because they’re excited about admin. The paperwork is the bit you do at eleven at night with the laptop balanced on your knees, and it is the bit most people rush.
It’s also the bit that decides how a bad day goes. Travelling alone means there is nobody else holding a copy of the booking, nobody else who knows which hostel you moved to, and nobody whose phone still works when yours is in a puddle. Almost all of that backup lives in one place, which is your email. An hour spent on it before you leave is worth more than any packing hack.
Everything routes through your inbox
Think about what you would actually need if your phone disappeared tomorrow. The address of tonight’s bed, the booking reference for the ferry, your insurance policy number and the name of the person you are meeting on Thursday. All of it is sitting in your email, which means your email is the account that has to survive.
It is also the account everything else recovers through. Bank, airline, accommodation platform, the SIM provider you would need to contact first. Anyone with access to your inbox can reset the lot without knowing a single password.
Set the account up properly, once
A dedicated secure email address for travel keeps bookings out of the pile of mail you already ignore, and it means the address behind your trip is not the one you have handed to every website since sixth form. Turn on two-factor authentication using an authenticator app rather than text messages, because texts need a working SIM and yours might be a Vietnamese one by Tuesday. Then write the backup codes on paper and put them somewhere other than your phone case.
Send one message to somebody at home containing your rough plan and how to reach you. Not a full itinerary, just enough that a person who is not travelling knows roughly where you should be.
Check the boring official stuff too
Entry rules change more often than blogs update. The FCDO publishes country-by-country travel advice covering entry requirements, safety and local law, and you can subscribe to alerts for the specific countries you are heading to, which arrive by email and go straight into the folder you have just set up.
Visa confirmations are the documents most likely to be asked for at an awkward moment, usually by someone in a booth with a queue behind you. Screenshot them. Border wifi has never once worked for anyone.
Then stop thinking about it!
The point of doing this before you go is that it buys you the right to ignore it entirely once you are moving. When you are deep in a route through somewhere unfamiliar and following one of those long guides you saved months ago, the last thing you want is a corner of your brain wondering whether you could actually prove your booking exists.
Solo travel is already an exercise in trusting yourself to sort things out. A tidy, well-protected inbox is just one fewer thing you have to sort out at the worst possible moment, usually at a bus station, usually in the rain, usually when the only café with power has shut for the afternoon.
