Set on 22 tropical acres on the Intracoastal Waterway, this resort is best known for its world-class marina and a rooftop lounge that spins every 66 minutes. If you experience vertigo after sitting in the revolving lounge, an invigorating body- or skin-care treatment at the hotel's intimate, exquisite European Spa LXVI will help relocate your sense of balance. Equally invigorating are the Hyatt Regency's recreational amenities, which include a three-pool complex with a 40-person hydrotherapy pool, tennis courts, and an aquatic center with every watersport imaginable. The hotel is in the process of updating and renovating into the 21st century, beginning with Grille 66 and Bar, a classy, upscale steakhouse. A $25-million refurbishment will transform the lobby, lawn, and remaining guest rooms with a retro modern decor. New lanai guest rooms have cherrywood furnishings and bathrooms with marble floors and granite vanities. All units have flat-screen televisions, wireless Internet access, and balconies with views of the Intracoastal Waterway and the hotel's lushly landscaped gardens. Designer suites come with a Jacuzzi, wet bar, living room, dining room, and exceptional views.
