London Travel Guide: What to Book Ahead, What to Leave Open
London is usually the first stop for first-time Europe travelers — and for good reason. It's English-speaking, endlessly interesting, and genuinely easy to navigate. But it's also huge. And it's very easy to either overplan it into a stressful checklist or underplan it and miss the things that actually require advance booking.
This guide is for the person who wants to know: what do I actually need to figure out ahead of time — and what can I just figure out when I get there?
How many days do you need?
Four to five days is the sweet spot. The city is enormous and even with the Tube you'll spend real time moving between neighborhoods. Four solid days gets you the major landmarks, a West End show, a market or two, and time to just wander. Any longer and London becomes a great base for day trips — Windsor, Bath, the Cotswolds.
And if you're pairing London with Paris — which is one of my favorite first-time Europe combos — 10 days total gives you a really satisfying trip without feeling rushed.

What to book before you go
A few things in London genuinely sell out or have long lines that timed tickets will save you from. These are worth handling ahead of time:
Tower of London — home to the Crown Jewels. Book in advance.
Sky Garden — one of the best views in the city and completely free. But it requires reservations and fills up fast.
Westminster Abbey and St. Paul's Cathedral — timed tickets skip the lines.
Churchill War Rooms — underground museum where Churchill ran WWII strategy. Genuinely fascinating, worth planning for.
Harry Potter Studio Tour — sells out far in advance. If this is on the list, book it the day you book flights.
West End theatre — London's theatre scene rivals Broadway. Popular shows go fast.
Afternoon tea — the good ones book up, especially on weekends.
Girls trip tip
Afternoon tea is one of the best things you can do in London with a group. Book it early — the iconic spots like Claridge's or The Ritz fill up weeks out. There are also great mid-range options if you don't want to splurge on the full experience.
What to leave flexible
Some of the best London moments happen when you're not scheduled. Leave room for:
Wandering Borough Market on a weekend morning
Ducking into a historic pub with no particular plan
Walking through Hyde Park or along the Thames
Stumbling onto street markets in Notting Hill or Portobello Road
And don't stress about "seeing" Big Ben, Buckingham Palace, or Tower Bridge. You'll walk past them naturally. London is incredibly walkable in the central neighborhoods — these things just appear.
The mistake I see most often
Trying to see everything. Switching hotels between neighborhoods. Scheduling every single meal. And suddenly the trip feels like work.
London works best when you pick a home base, book the things that actually require it, and leave the rest open. The city rewards wandering.
Day trips worth considering
If you have five or more days, London is a great base for a day out of the city:
Windsor Castle — a royal residence, easy half day from central London
Bath and Stonehenge — a classic combo, takes most of a day
Oxford — beautiful university town, easy by train
The Cotswolds — for couples or groups who want the storybook English countryside
