Walt Disney World has announced that Platinum, Platinum Plus, and Premier Walt Disney World Annual Passholders will be some of the first folks to experience Star Wars: Galaxy’s Edge at Disney’s Hollywood Studios.
Special preview opportunities are being planned and will be held before the land’s official opening on August 29, 2019.
Capacity will be limited and registration will be available on a first-come, first-served basis.
More information and registration details for previews will be shared at a later date, so now is a good time to verify that your My Disney Experience account is using an email address that you check often.
