I wonder if you could build a multi-level resort with deluxe, moderate, and value all represented. Each would have its own pool section and eateries. I know that those in the deluxe might gripe about the value crowd but you could use room keys as gates to each pool. For the restaurants, there would be no way to really control it.
Each section could be themed differently. The value like a European village, moderate like a little more plush estate, and the deluxe like a castle or lord's manor. It might difficult to pull off, though. It wouldn't need a European theme but that was just an example.
