The hotel would seem to line up with what I've been trying to piece together. It could be oriented away from the backstage buildings, so one side overlooks the parks and the other side overlooks a lake.
But the notion in the article that there just is not enough space for a standalone CW2.0 is a bit ridiculous. I mean there is space, it's just a matter of how they want to use it. I rather do not like the idea of it splitting up the themepark. I know we were all taken back buy the size of this place, not as impressive if 1/3 or so isn't actually in the park. It would also further restrict the possibilities of the shopping area.
I will say having the paths to separate immersive areas is not so much a problem if the paths are big enough, but the hub doesn't need to be outside the park for this to be done (like the Diagon example). Adding ticket gates at each does open it up to more problems.
