This was an awesome tour. We saw everything we wanted to see and more in five hours. Our tour guide, Ross, was very knowledgeable and entertaining. He provided lots of background/history information on the different areas that we would not have known if we went out on our own. Even though we were on a shuttle bus, the tour still involved a lot of walking and stair steps and Ross stayed t with the group the entire time. We would highly recommend this Grayline tour
