Our experience with the tour almost did not happen. Our guide was late and did not meet us at the designated location. We started the tour on our own. He finally texted me and met up with us where we were in the museum. While it was a bumpy start, he apologized and then basically worked with two out of the four of us. He seemed knowledgeable and was pleasant. To make up for the lost time, he stayed longer with us on the tour which was the professional thing to do. I would suggest the tour guides wear something bright or clearly marked so it would be easier to locate them before and during the tour. Our guide wore jeans and a tee shirt with a black sweatshirt. Not really official looking given the cost of the tour. He did know some interesting facts and was very respectful when we finally got going with the tour.
