The super-swank Main & Sky is rich in amenities—with a rooftop cocktail lounge, soaking tubs in the spa, and sprawling suites that are great for groups. With bathtubs that fill from the ceiling, the suites feel more city-chic than ski-town cozy. Upstairs there’s an indoor-outdoor cocktail lounge; downstairs, a heated lap pool and soothing spa. Plus, they throw in local shuttle service.
