The people willing to pay that price are not in high supply, but ARE in high demand. We just had very wealthy friends leave GF after 2 nights. Felt they were not getting what they paid for and moved off-site. Said "Disney should be ashamed" charging those prices for an outdated suite with old beds. The manager practically begged them to reconsider. Offered to bring them to other resorts and show them other suites until they found something they liked. My friend said it was almost uncomfortable, like he thought the guy was going to cry.
They want that business. They are losing it to the proliferation of off-site high end resorts that outclass the Disney deluxe. This matters, trust me. We have several friends who only stay off site. The accommodations are "incomparable" according to people we've talked to.
