Add Peter Pan's Flight to the list of attractions you can't experience for part of the summer. Disney's calendar has this shutdown.
Tiana's Bayou Adventure will open this week but with one opening comes more closings. Already at EPCOT, Test Track will be out of service for the summer, and Rockin Rollercoaster is also currently out of order for the foreseeable future.
According to the Disney calendar, Peter Pan will be out of service from July 8th to August 21st for refurbishment. Over a month and a half of being down. For some reason, that ride remains one of the most popular attractions at Magic Kingdom.
In Frontierland, M.K. silenced the Shootin Gallery early in the week for good. One of the park's original attractions will not return in any form. Just a couple of doors down, the newly rethemed Country Bears Jamboree will open on July 17th, so at least there is that.
There will be far more closures to come, especially at Animal Kingdom where DinoLand USA will close down as it undergoes a full remodel that is expected to bring an ENCANTO theme to the area. In addition, Dinosaur: The Ride will also close down for an extended period of time as it is rethemed to an Indiana Jones style attraction.
Disney will invest $17 billion over the next 20 years into the Disney World parks, and those changes should start in the next couple of years. Disney is also reportedly going to add to the Magic Kingdom park behind the Thunder Mountain Railroad attraction. It is still up for debate on what it may feature.
