I did this trip with my mother last year and we both loved it!!! The 7 Hours flew by... there was so much to do and see... I was hoping that it wouldn't end. The tour guide was great... she gave us a lot of information.
The lunch was wonderful... our tour-mates were a lot of fun too!!!
I don't think that there was anything that could have made it better... ok, maybe if it went on for another 8 hours and we got to see even more. Everything we did see was a lot of fun and very informational.
Just a warning... no matter what your age is... make sure you bring your ID. There were two individuals on our tour (both over 40 - no where close to the 16 yo age requirement) were sent back to their hotel rooms to get their ID and they missed the first hour of the tour.
