New York City

The Big Apple has it all--from holiday entertainment (see the New York City Ballet perform The Nutcracker at the New York State Theater at Lincoln Center) to simpler pleasures (join the crowds ogling the window displays at Lord & Taylor, Barneys New York and Bloomingdale's).

Stay Affinia Dumont This gorgeous hotel in the city's chic Murray Hill neighborhood has everything you need for a fit holiday, including a state-of-the-art fitness center and spa and a sneaker valet who freshens and cleans your workout shoes daily. There is also a fitness concierge, your one-stop resource for calorie-blasting fitness activities in and outside the hotel; she can even arrange for the delivery of weights to your room.

Sweat City Climbers Club Scale Manhattan's first climbing wall at the W. 59th Street Recreation Center, just a 10-minute cab ride from the hotel. In addition to 11 belay stations and more than 30 routes, the center has a "bouldering" cave where you can practice climbing moves close to the ground without ropes. Day passes are $12 and include ropes, climbing shoes and harness rental plus use of lockers and showers (533 W. 59th St.; 212-974-2250, climb nyc.com/ccc).

Pose Jivamukti Yoga Center An easy walk from the hotel (about 26 blocks, or a little more than a mile), this beautiful and very colorful yoga studio, with Buddhist statues and a small flowing wall waterfall, offers 95-minute Jivamukti-style classes (Hatha yoga with chanting, meditation and music; $17 plus $2 for mat rental; 404 Lafayette St.; 212-353-0214, jivamuktiyoga.com).

Indulge Affinia Fitness Spa Having a spa right at your hotel means you don't have to travel for luxury treatments. Try the one-hour Affinia Fat Burner, which combines a seaweed/algae wrap with a Vichy shower, dry brushing, a scalp massage and moisturizing lotions to minimize the appearance of cellulite. OK, so this treatment doesn't really burn fat, but it's guaranteed to make you feel relaxed ($110; 212-545-5254, affinia.com). Another option: Head 23 blocks north to the uptown Bliss Spa, one of the city's trendiest pampering palaces.
