One of the best tours I have been on. Highly informed tour guides with the exception of one. Even the bus driver advised a couple to get off and take another bus!!! I won't comment further as this driver was pretty rude to the guide and a pedestrian!! Guess she was having a bad day. We had a two day pass and got off and on many times to see the sites. Since our hotel was within a block of one of the stops, we used this as our means of transportation which worked out great.
