This is a great way to see a lot of London at one time. It is the now familar ferris wheel across the Thames River from Westminister Abby, Parliment. It is a 1/2 hour trip from beginning to end, costs about $15, and you should make reservations during the high season (June-August). Each is capsule is huge, able to hold 20 or so people and there is very little vibration. The view is spectacular.
