Riviera Resort Hotel, Hallandale, FL ca. 1975
The card states that not only does the Riviera feature rooms, but also "villas." They are "artfully" distributed, too - not just placed randomly as in most hotels. From the road, I would pin this structure as a car dealership. The first thing I'd ask the desk clerk is "where are the new 1976 Sedan D'Villes?"
