- Walking tours—especially early-access, small-group, and after-hours experiences—often have limited capacity, so booking at least two to three weeks ahead is recommended during peak travel months.
- Wear comfortable shoes suitable for cobbled paths and historic staircases, and arrive 15–20 minutes before your scheduled departure, as guides cannot wait for late arrivals.
- If your tour includes upgrades like the Thames River cruise or Tower Bridge, allow extra time afterward rather than planning another attraction immediately.
- For the quietest visit to the Crown Jewels, choose an early-access departure whenever possible.
