How was your experience?
Although we had seen the monuments numerous times before, we learned a lot on this visit. The tour was brand new, which you could tell at times. All in all, I think this will be a very good tour, once the guide really gets the hang of it. I don't think it will ever be a 2-hour tour though. With all the tourists hanging around the monuments, it's just not possible to walk at a brisk pace, so make sure you save more than 2 hours. It would be useful for the guide to have a bright umbrella or something similar. She was not tall and we lost her in the big crowds at one point and only found her about 10 minutes later.
