hmm.. interesting. Does Disney do any "all inclusive" stays anywhere else currently? Are the cruises? It looks from the surveys (which floated a price point of 1000 per person for two nights), that that might be the concept.
A cruise ship is the best analogy. It's a hotel on water. The food and ship activities are usually included (they do have upcharge fancy restaurants and experiences, like lessons from a pro golfer). They may have an off-ship excursion for free (when they stop at their private island). The big charges are liquor and off-shore excursions (paragliding, tours, zip-lining, scuba diving) that are a la carte.
I imagine SWResort to a be a three-day two-night cruise with shore excursions to SW:GE. Probably the only thing not included would be alcohol (and most cruise ships offer a package for open bar).
