My employer made all of us service managers take the "Disney Magic" course over three days at Disney World in 1990.
The most interesting part of the course (and the only thing I stayed awake for) was the tour of Unter Disney World.
Disney World is actually the second layer of the enterprise, built over all of the offices, maintenance shops and warehouses. All of the overpriced merchandise reaches the shelves above ground from below so the marks, I mean tourists, don't see any clutter, carts or shift changes.
Finding out that I'd spend an extended period in the park as part of my training (in a costume, as a street cleaner, a ride operator, security, retail, etc.) was odd, but understandable, because this was pre-Eisner Disney and there really was a Disney culture that you had to learn (or so I was told).
However, as a child growing up in LA, I'd probably been to Disneyland 15 times and was still bright-eyed and innocent about the Disneyland and Disney World parks themselves. The tours under the park and the tour behind the Main Street buildings was a shock. Man, that place generates trash, and the number of stuffed characters being shuttled underground from retail outlet to retail outlet is amazing.
At the parade staging area, Goofy had his head off and held under one arm, with part of his upper costume pulled down over his shoulders (he was wearing a "wife-beater" t-shirt) and was sharing a cigarette with Snow White. Apparently, either smoking in costume (even with your head off and hidden in the staging area) or wearing the t-shirt, was a MAJOR no-no. The executive riding with me in the double-seater golf cart made the driver stop. He lectured Goofy and Snow White (out of earshot).
The tour ruined Disney's mystique for me. I've taken my kids to Disney World six to eight times since then and every time I see Goofy or Snow White in the parade, I picture wife-beater Goofy passing the butt to Snow White so she can take a long, deep drag.
