The other trick is that there is no space between the monorail station and the entrance to put a marquee hotel; just the pool area would consume most of that space. They would have to go quite vertical, and even then, it would still have to allow a huge volume of people to pass through it to get to the monorail.
I do suppose - and this could be interesting- it could envelop the monorail terminal similar to the contemporary.
As much as I could appreciate the idea of a hotel done well to enhance the entrance, it would need to be done well.
