How it works:
- You may encounter touts offering tickets for a sightseeing bus at Trafalgar Square.
- The tickets may look legitimate but are in reality not tagged to any company or vehicle.
Places to beware:
- London: Trafalgar Square
What to do:
- Only buy direct from company/official counters or licensed retailers.
- Alternatively, online day tour platforms like GetYourGuide (best in Europe) also has several popular bus tour options.
