My son and I decided to do this and we had a blast! It should not be missed. You will see a great part of the town and mountains and see things you are never going to see on foot or by car! They do not tell you about the insurance until they have you at the store. This frustrated me greatly. It is like the rental car schtick in the US, but other than that, great. Our guide was especially good and as far as we were concerned saved the day! Go do this when you are here!
