Cabana Bay draws influence from many sources, mostly the time period it is derived from. For the most part though, all the building aesthetics are themed to New Jersey beach resorts. Obviously, they are going to use lush tropical landscape. Why would you landscape a resort in Florida to a northeastern seasonal beach town that a large volume of your clientele are trying to escape? One thing people from up here almost always need to see on a vacation to a warmer climate is palm trees. This doesn't make the resort tropical.
50s/60s Roadside/Seaside beach motel is the theme. Other than the greenery (which was an obvious choice), nothing screams "tropics" about CB.
