Here's some of the progress being made on a more complete and thorough design for the thermal resort suspended precariously above the greater Gastric Sea. Lots of brutalism and 1960s space-age inspirations for the overall architecture, with a healthy dose of the WDW Contemporary resort in the terraced room layouts. (Not visible in this view is the thermal spa itself, which would be sort of buried under and behind the main lobby section)
I'll probably end up doing some kind of cutaway for this like the Lower Visitor Center, but I'll also use it to produce some floor plans similar to what you'd see on the back of a hotel room door.
