When talking about the cost - does everyone realize it's an experience resort? From when you check in, you are given a wardrobe to wear for the duration of stay, you are a character in the Star Wars universe. You have interactive experiences that regular Disney guests won't have, an entire story built around you.
I think Disney is crazy expensive, but honestly $1000 seems worth it for fans who would love this kind of thing. I'm sure the hotel won't be as large as others. I'm betting people will book for a 2 or 3 nights and then go home - the experience being the sole reason to book the trip, not a Disney trip. And then there are people who will begin/end a regular Disney trip there with a couple nights. I bet it will be quite popular.
