If the hotel is easily alterable (and I'm not convinced it is, given WDW's shortsightedness and Imagineerings inability to do anything on a reasonable budget), its part of the problem. They would have essentially created a "black box" hotel that can be altered to other stories and themes, but that adaptability would have cut into the richness of detail and intricacy of design that should be expected at this price point. For what they are charging, the story and theme should have been built into the structure from the ground up, deeply embedded in every inch of the building. Diagon Alley and Battuu can't just overlay another theme. I admit that the cheapness, flimsiness, and lack of character in everything we've seen make it seem very changeable, but that's no plus.
