One of the London sites you're seeing frequently during coverage of the 2012 Olympics right now is the London Eye. My daughter and I rode the Eye last year, and we had originally intended to do it during the daytime hours, but we kept putting it off until we had no choice but to ride it late in the day. We hopped aboard our last night in London, just as the sun started to set, and I'm so glad we waiting until then. It was wonderful to see London light up before our eyes, and it was a memorable way to wrap up our stay in such a fabulous city. First of all, I recommend you go to London if you ever get the chance. Secondly, I highly recommend riding the Eye at sunset.
