Pretty much nailed it with this post.I can see merits to both sides; personally, Walt's Apartment and the Matterhorn Basketball Court are the last two areas of the park I haven't been to that I still would love to see, but that's just me. Some people don't like behind-the-scenes/spoilers, and some do. What I DO find funny is that many seem to forget that Disneyland has always (from day one) had large corporations serving food and selling merchandise within the park. Here's a quick list of shops/restaurants sponsored by corporations from the early years: Gibson Greeting Cards, INA, Coca Cola, Hollywood Maxwell Intimate Apparel, Bank of America, Sunkist, Kodak, Blue Bird Shoes, Carnation, Swift Premium Meats, Upjohn, Maxwell House, Hills Brothers, Aunt Jemima, and Wurlitzer. Walt himself knew how to use the money of other corporations to get what he wanted done. The difference from "back then" and "today" is that the stores from 50-60 years ago have a veil of nostalgia and warmth wrapped around them. Although I'm not a fan of the food of McDonald's, I find them no more evil or revolting than Coca Cola, which has had a spot on Main Street from the start.
I also see merit in comparing tours of Walt's Apartment to tours of homes of other historically significant figures. Most of the important family heirlooms were removed years ago; what remains is either a replica or replacement. I don't really see the opening up of Walt's Apartment as another piece of proof of the Disney Corporation's slide into moral or ethical decay. It became inevitable because more and more people heard about it and they wanted to learn more about him, even if it means paying a few bucks to see it.
It's a little disheartening to hear the repetitive "all they want is money" mantra over and over again. Without that money, Disneyland wouldn't be as clean as it is, as well-designed, as well-landscaped, or as full of entertaining things to see and do. Initially, DCA was a huge blunder and an error in the history of the Disney Corporation, as they underestimated what the public would pay to see if they slapped the Disney name on it. Ever since the 50th Anniversary, I have seen a huge turnaround in both parks, as they have attempted to please both sides of their fans: the ones who just want to have fun, and the ones who want Disneyland to be just like it was 50 years ago. It's a tough scale to balance.
