Join me, together we can rule the galaxy.
What the high-end hotels lack is the resort/destination feel. But just wanting high end hotel experience is there.. Peabody, Ritz, Gaylord, etc. But none of those are destinations in themselves. I doubt building a ultra-lux hotel would drain those people away from the Poly/GF/etc. Why? Because they obviously aren't paying for the Poly/GF because of the ultra-lux services and amenities (they don't exist!). They pay because they want to be in the Disney bubble and can.
You hit the nail on the head... Guests stay at Disney Deluxe resorts because of location, location, location. It is the oldest rule in real estate.
