Stay at the heart of the action, in this central hotel. Part of the Hyatt Regency Group, it has a modern design, with neutrally decorated interiors accented by bolder touches. 693 guestrooms are spread across 24 floors, each with iPod docking stations, 55-inch flat-screen televisions and coffee makers. Outside, you’ll find a swimming pool, spa tub and sundeck on the Hyatt’s third floor. Plus there’s a 24-hour gym, with cardio and weight-training equipment, complimentary bottled water, and towels. But its crown jewel is The Compass Restaurant, Arizona’s only revolving dining room (floors 22 and 23 house the mechanical equipment to ensure it keeps moving).
