I was worried about riding the bike but needn't have been. Our tour guide, George the Great!, made absolutely sure I was comfortable before we started and checked on me often. We walked from our hotel and were able to find the pick-up location on our own. As it turned out, we were the only 2 who had signed up so we got a private tour. George was personable, very knowledgeable and funny. It was a great morning and gave us a good feel for the city while showing us all the major sites. At the end of the tour, George took the time to review a map with us and point out other areas we should visit, great areas for restaurants, etc. I am glad that we did this on the first day and highly recommend it.
