I think that's true for length of stay in the resort. Think of it as a cruise--you're on the boat 3 days, then switch to a hotel and spend a couple days on your own in the parks. Only here, it would be 3 days on a starship, then 3 days at Poly or Beach Club.
I'm still not convinced the Venn diagrams of "really rich people" and "Star Wars fans who like to LARP" overlap enough to make this work. Maybe 2-day stays, but anything more than that, I just don't see it. Or it'll be a bunch of parents out-of-costume with the cell phones out documenting little Johnny's adventure and killing the mood. If I had Photoshop skills, I'd make a version of the concept art with surly Goth teen siblings and strollers added in.
