The tour is divided in two parts, they have a short break so you can go into a store and go to the toilet and buy water/drinks. I felt that the tour was too long and should have ended when the break was. Also the tour was too expensive.
The first part of the tour was informative. The guide was however trying too hard to be funny and that did not work at all.
A few small things to fix such as the length and the script for the guide and then the tour would be excellent.
