The London Eye
One of the first things we did in London was take a "flight" on the London Eye. It was a fairly clear day and we had a great view of Westminster, Charing Cross and Big Ben. None of us felt any discomfort on the Eye, it moves very slowly and feels completely secure. After that we took a short River Cruise.
