Especially when Walt was in charge. When Disneyland stops changing, it's dead.
But taking Jessica out of the trunk of the car is not change, it's clumsy and artless removal.
Walt didn't change Adventureland in the 1960's by adding more barrels, he added the Treehouse and the Tiki Room and the Tahitian Terrace. Then he let Marc Davis add laughs and sight gags to the Jungle Cruise. And he let Rolly Crump redecorate the Bazaar.
Walt removed the Chicken Plantation restaurant in the early 1960's, but he replaced it with New Orleans Square and two of the largest and most popular E Tickets in history that remain wildly popular 50+ years later.
Walt changed Fantasyland repeatedly. He added the Skyway in '56, Alice in Wonderland in '58, Matterhorn in '59, Small World in '66. He changed Canal Boats of the World into Storybook Land, and put a pirate ship selling tuna sandwiches in there just for fun.
The rather useless Mickey Mouse Club Headquarters became Great Moments with Mr. Lincoln. Tomorrowland went through more changes and more upgrades than you can count. Frontierland expanded, herds of animatronic animals were added, and even dinosaurs showed up along the Disneyland Railroad.
A changing Disneyland was always an improving Disneyland, Walt and his Imagineers saw to that continually.
This latest "change" is not improvement nor is it really change, this is only clumsy and artless removal per HR. Any Disneyland fan should worry about its broader implications.
