Arizona's best Roald Dahl-style "Great Glass Elevator" is at the Hyatt Regency in downtown Phoenix. It whooshes you skyward to the 24th floor, the home of the revolving Compass Restaurant. As you shoot up, it's fun to lean forward and place your forehead against the glass, giving yourself just a drop of vertigo. At the top, if you're feeling flush, grab a cocktail or bite to eat at the restaurant, which rotates slowly atop the hotel, giving you one of the coolest views of the Valley. Otherwise, just stand around like a looky-loo for a few minutes, and then enjoy the elevator ride back down again.
