I think this is going to be themed, from the ground up, ....
And it's going to be a MUCH deeper level of theming than a building style and matching uniforms.
I guess you'll be able to hang in your room and watch the holotank for two days if you want, dialing up blue milk from room service, but I can't really see why anyone would want to, consider the price of the place.
But it's not like, a hotel with some activities. The entire thing will appear, to everyone in it, to be a fully operational battle st.. er.. spaceship. All of the things going on around you will be geared to a storyline, which then has branches and twists for people who want to follow them.
On deeper though, sure, there will probably be a gym inside somewhere, and a pool. And maybe even a running track.
So far, yeah each to their own, but ....
But it's not like you are going to be able to pop out the big glass doors on the front of the building and go for a jog easily, nor slide a hidden window open on your room, etc.
Dunno. We'll see. With the amount of time and effort they are investing in the 360 concept, I think people are just expecting a "better" resort. and I don't think that's what this is.
