You haven't been to many roadside motels then. Most have names disproportionate to their look/location.
And this evokes the feel of many east coast beach motels. It's a fitting name.
I've been to plenty of roadside motels over the years. Though many of them have disproportionate names, the disproportionality tends to be an aggrandizement of the motel's features or status, not a wholesale referential shift in geography. (For example, a dilapidated motor inn called the "Grand View Lodge," which overlooks a barren field.)
Moreover, the press release refers to "motor courts just off the highway," not specifically to "East Coast beach motels." While there are beach motels that are "just off the highway," the broad language of the press release clearly has the effect of evoking road trips generally, and not East Coast beaches in particular.
However, while there do exist some roadside motels with names that are completely inappropriate for their location, that fact is beside the point. What's important for the purposes of this particular resort is the extent to which
its name is appropriate to
its function and role, in the context of its location in central Florida.
Put another way, a name can be too clever for its own good. In regard to Orlando-area resorts, the general public is likely to associate a resort's name with a literal reference to its theme, simply based on precedent. Even if there are a handful of tacky motor lodges in the middle of the U.S. with grandiose names like the "Polynesian" or the "Royal Pacific" (each justifying their moniker with a few plastic tikis and leis strewn about the lobby), the typical Orlando visitor is likely to assume that resort hotels with those names are going to literally evoke Polynesia or Pacific islands.
I would bet that the overwhelming majority of visitors who first hear of the "Cabana Bay Beach Resort" are going to associate the hotel with some sort of tropical beach theme. Although they might learn quickly enough that the hotel is in fact nothing at all like the Caribbean Beach Resort over at Disney, why create that extra layer of confusion -- and possibly annoyance, for those who book their rooms without doing all their research?
Don't get me wrong -- I think it would be a nice trend to start having resorts whose names aren't necessarily so on-the-nose with the hotel's themes; I just don't think this specific example is the best way to start.
