My dream at the moment is for universal to just tell us how many parks they are planning to build, because it completely changes the calculus of what they can do given the limits of the land they own. If they are just doing one large dry park then the idea from
@Disneyhead of an entrance hotel and 4 themed hotels could be great. If they instead want 2 dry parks, then the parks probably have to be smaller and narrower, and the hotel situation might be limited to a citywalk hotel and 1-2 themed hotels for each park. I find it so so hard to even conceptualize ideas of how they could do things when the question of how many parks they are fitting in totally changes things.
Also FWIW, I think it is good to have connections between lands without forcing everyone into the hub. That being said, they should certainly put a lot more effort into creating facades and natural cover for those places so that immersion between lands is preserved as much as possible. There is no reason they couldn't have Diagon style entrances to a land coming from other lands as well as the hub.
