Having just returned from a wonderful trip to the French Loire and Eure-et-Loir valley and then on to London for a few days, I will report more in detail on my trip, but I want to advise you of a new and fun way to tour the city. It's by a Pedibus ( see below). I did not take one (to much exercise for moi!) but saw plenty of them all around the city. They have theme tours, like a pub crawl or market tour.
With a seating configuration similar to that of a dinner table, The Pedibus is the most fun and sociable way to cycle, chat and hang out with friends or people you have just met.
