This is an interesting point. Even on a cruise ship, which I see this experience often compared to, you get the outside and also the wonder of the ocean to ease your mind. I guess this is just a gamble on Disney’s part. I don’t dislike seeing them take some chances, it’s just that I think they proceeded with Star Wars because everyone assumed it was a can’t miss. I just don’t think that assumption is correct.
The bigger issue is circadian rhythms and how tied to sunlight those are. Artificial light isn't the same thing. People are going to feel weird in this hotel. Not to mention, possible motion sickness issues if you are "moving through space" but the building isn't actually moving.
