DW & I just got back from the world and we took the BSM tour. What a time! We were supposed to be with a group of five, but the others cancelled out that morning, and we got a private tour!
You start in Epcot, and we saw the inside of the American pavillion as well as the ride mechanics of Body Wars. We also saw the costuming areas and repair shops. We then moved along to MGM where we saw costumes being made - what a process! We saw them making Ariel's new costume (they were cutting each scale of her fin), and then had lunch at Mama Melrose's. Luch was served family style, complete with appetizer, two entrees, and our pick of dessert (the chocolate mousse is to die for!). We then made our way to MK. We went behind the scenes to see the staging area for the parades, and saw the barges that carry the electric water pageant.We then went to the specialty shops. We saw the metal, carpenter, and sign shops. We learned about Cindarella's Carousel and the horses, and we saw several of the new Epcot ride vehicles being made. We went into the largest Christmas warehouse we have ever seen, and then went into MK to see the utilidors. Afterward, we were escorted down Main Street and told stories obout each of the windows and the significance of the writing on them. We finished by watching the afternoon parade.
If you have the opportunity (and the funds) to take this tour, it is well worth it IMHO.
