This tour is great, and I highly recommend it. Check out the discounts for DC, AP, or the Visa Card to save 15% if the cost is an issue.
The tour starts on Main Street and the guide points out all sorts of things that you wouldn't even notice if you weren't looking for them. You also get to hear some of the history of the park. On our tour, we rode Pirates of the Caribbean, Jungle Cruise, and Haunted Mansion. Lunch was included in the price, and was at the Columbia Harbor House. We also went to the parade staging area and got to see all the floats and the area where the parade starts. After lunch we went down in the utilidors. There is a lot of walking, but the guides are good at finding shady places to sit and rest while they talk about different things. I would definitely recommend this tour to anyone!
