I read that each of the four parks in Florida will be celebrating along with
Disneyland.
"Each theme park will honor Disneyland's birthday by introducing new shows or attractions. Hong Kong Disneyland will apparently celebrate simply by opening sometime during the promotion. With few exceptions, the new additions to each park are simply concepts borrowed from other resorts. The press release detailing Walt Disney World's new additions goes so far as to boast that the resort is importing attractions from other Disney theme parks.
