Galaxy's Edge has a narrative: the park is a physical rendering of the planet Batuu, which is apparently gripped with a confrontation between the Resistance and the First Order. You'll be able to helm the steering wheel of the Millennium Falcon, and reportedly absorb other attractions drawn from older movies in the Star Wars franchise.
But Disney isn't stopping with two fully-immersive theme parks. Disney World will eventually be home to a Star Wars-themed hotel, where guests will dress in the appropriate attire and interact with some familiar faces from the franchise. Guests shouldn't be hoping for a restful stay, either: at the hotel, you'l be recruited for missions by the staff, and your performance will determine whether you get paid (in the form of extra hotel credits), or if bounty hunters start tracking you for retribution.
