I bought my tickets on Groupon so I got a better price then on their site. We enjoyed the double decker bus and it was a nice day! My husband is tall 6'5" so he had a tough time in the seats but that's not the first time. My son's 6'2" and 6'3" fared a bit better. The tours were informative but it truly depended on tour guide. We had great ones, Kevin and Karen and had 2 others...One I couldn't understand a word she said and the other must have suggested tips at every stop! That was the turn off!! I think some of the information was rehashed and could have been presented better.or more entertaining!!
