We have done this tour twice. And yes it is worth the money it costs. You meet at Guest relations at the front of Epcot. There the put on a bus to take you around. The first place we went was to the American Pavillion and went under to see how it worked. We went to MGM and ate lunch at Mama Melrose. We also went to MK and went underground to the tunnel and saw what that was like. We also were taken to Central Shops, Costuming and the warehouse is for the Xmas decorations. We also saw where they store the floats for the the parade at MK. On the bus they have bottle water for you to drink. I would tell anyone if they can afford to take the tour as they will not be disappointed.
I think the tour is worth every penny. You will be amazed at some of the things you see. I took this tour with my high school son years ago, and this year I'm going again with my husband. You may lose a little of the magic having gone on the trip, but it is just so interesting.
