I get the frustration with Disney for charging money for things that should have been included in SW:GE. But Disney has found that people will go to the Parks even if they raise the prices and don’t include many immersive/interactive/streetmosphere elements. And then they discovered that some (many?) people will pay exorbitant amounts for those same elements when concentrated with a storyline.
As mentioned long ago in this thread, I could see Disney adding additional versions of this concept for Adventureland, Tomorrowland, Fantasyland, etc. If they can get pricing down to something remotely reasonable (”reasonable” from my perspective), I think this could be an interesting innovation for the parks.
