Walt's greatest legacy, Disneyland, slipped into maintenance mode for a long while. Part of the problem had to do with all the Walt-hugging preservationists. Anything the man touched had to be treated like an archeological relic. This sentiment was by no means isolated to the employees of the Walt Disney Company. Many fans took it upon themselves to argue on behalf of leaving the classic Disney attractions undisturbed. They would prefer to limit Disneyland development, in order to maintain the park as a shrine.
Finally, almost 20 years after Walt's death, the company realized that they had to start making hard decisions or attendance would shrivel up. So beginning in the mid-1980s there has been a series of sweeping changes. As particular rides become stale and lose popularity, they are rethemed to draw attendance. Most of Tomorrowland was gutted and replaced in 1998. The Swiss Family Treehouse became Tarzan's Treehouse in 1999. In 2002, the Country Bear Playhouse was bulldozed to make room for a Winnie the Pooh ride.
This stuff doesn't sit well with the committed Disney fanatics. Walt Disney Company chairman Michael Eisner experienced this firsthand in 1985 during an interview with a newspaper reporter:
"On the 30th anniversary night, I came down here with Frank [Wells] and the writer from the New York Times. And I was proudly telling about all the things we were doing at Disneyland, and I got to the George Lucas 'Star Wars' ride... 'We're going to put in this great Star Wars attraction with technology that has never been seen before. It's gonna be the attraction that's going to replace that dog, [Adventure Thru] Inner Space.' She said, 'How can you say "that dog?" That's the most brilliant attraction ever at Disney! Walt Disney himself designed it! How can you ruin Disney?' She then dragged me to go over on it. We rode it twice. She called me a monster."
That's when Eisner realized that, to the fundamentalists, changing anything in the park was immoral. And changing anything that Disney himself had personally created bordered on blasphemy.
The hardcore fans would like to see the place declared a national monument, to preserve what remains of Walt's original vision. In their view, the best thing would be if somehow the entire park could be hermetically sealed, stuck behind glass just like Walt's office down on Main Street.
