We did this tour in January. I believe the
AAA or Annual passholder discount is 10% - 15% but the Disney Visa discount was 20%. We didn't need a park pass that day and lunch at Mama Melrose's was very nice. Our guide, Kris, was just wonderful. My husband is the Disney zealot and I like WDW well enough but don't consider my self a fanatic. I thought that 7 hours was going to be a bit of a stretch for my attention span but it went by remarkably quickly. We started with a behind-the-scenes look at the American Adventure and got to talk to an engineer that had been w/ WDW since before the first park opened. He was a man who is passionate about his job and that made it very interesting. The back of the the American Adventure was impressive. We had our first look at forced perspective there. We went to Cast Member services and I enjoyed seeing all of those uniforms.
We went to the Christmas decoration storage fascility and I really thought that was going to be lame but it was surprisingly neat because we could pretty well pick out where a particular decoration was from just by the theming.
We went to the shops where ride vehicles were designed, painted, etc.
We saw costume cutting & patterns at MGM.
We went to the Utilidors at MK and learned about Disney's garbage system...leave it to Disney, they even make a profit on that.
We saw the backs of buildings.
We saw the Share a Dream Come True parade and learned more about forced perspective.
We had many, many opportunities to ask questions.
It was a very nice day.
