The Disney Parks blog has announced the starting date for Seasons of the Force at Disneyland: November 16. Star Tours will get a new scene inspired by The Force Awakens (probably Jakku) and the Star Wars Launch Bay will open. This will also see the limited-time reskinning of Space Mountain as Hyperspace Mountain and a new version of Jedi Training that will incorporate Rebels characters.
There will also be “an opportunity to revisit favorite scenes from classic Star Wars films,” which sounds like there’ll be no special The Force Awakens preview at at Tomorrowland Theater.
Details for the version at Disney World’s Hollywood Studios in Orlando are forthcoming, but I expect most of this (except Hyperspace Mountain) will be doubled there.
