Plunge at the Gansevoort South Hotel, Spa & Residences

Miami has outdone itself once again: a 26,000-square-foot rooftop nightclub — one of the largest in the Americas — has just opened atop the new oceanfront Gansevoort South Hotel, Spa & Residences. Called Plunge, the over-the-top playground features chandelier-lit cabanas, an elevated 110-foot-long pool, a dozen palm trees, and a granite bar. The highlight is the view: to the west, the city skyline; to the east, the vast Atlantic.
