I agree, but remember that the cost won't be ~$1000. Sure for one person it will be, but who's gonna do this alone? The cost is gonna be like a cruise ship and it's gonna be north of $1000 PER PERSON. So for a family of 4 or 5, that's a VERY expensive and hard to justify stay.
I don't think this is aimed at a your average family of 4 or 5 though as much as it is families with money to blow. That's where the main issue comes in is that the ones with the money to blow isn't their core audience. Those are who Disney likes, but you can't rely on them.
What's the price estimated to be?
It's a small enough hotel that they can cater to the very wealthy who won't think twice about paying $1000 a night, hell for the wealthy, it's probably not them booking the trip.
