London: 24-Hour Hop-on Hop-off City Cruise

About

Grab this ticket and get 24 hours to cruise up and down London's famous Thames which runs the length of the city. The boats depart every 30 minutes, every day of the week, from three different piers: Westminster, the London Eye, and the Tower of London. So rather than a one-time boat ride, you can treat the cruise as your main transport method. Like the tube, but with waaaaay better views.
