After a spell of overexposure, the unofficial capital of South America has been officially reinstated as a high-wattage, high-profile American urban center. Ritz-Carlton recently unveiled an oceanfront resort in a Morris Lapidus building in South Beach, but the action isn't confined to Collins Avenue: downtown has a new Four Seasons, and North Miami Beach is also welcoming development (the New Urbanist Aqua condo complex) while preserving its Miami Modern architecture. This year, the Deauville Beach Resort will be sprucing up its kitschy icon. André Balazs and Canyon Ranch, meanwhile, have targeted landmarks for their latest projects (the Lido Spa and the Carillon, respectively).

Deauville Beach Resort

Located in North Beach at the heart of Millionaire's Row, the Deauville is one of Miami’s “Grande Dame” hotels, with distinct MiMo (Miami Modern) architecture. The property once hosted Rat Pack members such as Frank Sinatra and Dean Martin, as well as Elvis Presley. Today, its location about 25 minutes from South Beach draws travelers seeking a quieter Miami retreat. The hotel has 484 rooms, including seven junior suites. Most have ocean views and are outfitted with white walls, white bed linens, and white headboards. Amenities include on-site "Floribbean" restaurant, Café de la Mer; a jazz club; and a tiki bar.
