My comparison was hyperbolic, yes, but theme is beyond just re-creating a time or place in the world (fictional or real). It's about telling a story. Evoking emotive experiences in the guests as they make their way through the story the designer is trying to tell. I suppose I mostly just fail to see how this hotel design tells the story of Walt and his travels through the European Riviera.
I didn't stay there but I thought the common areas had a certain charm. Reminded me of MGM in it's hey day in spots. I found it to be self-referential without being kitsch.
The thought of the resort being a "walk along the Mediterranean Riviera" would have been great if they would have massed the building to reflect differing building typologies, thus reinforcing the story that the guest is making their way from Italy, past Monaco, and into France. Would have been light years ahead of what they are building. Unfortunately, the monumental form does not lend itself well to the idea simply by being a single mass, despite being the most cost efficient approach. So one is left with a distilled, vague European Med Coast Riviera Walt's Travels "theme", instead of a cohesive story to present to the guest.
