Smuggler's Notch, Vermont; 800/451-8752; www.smuggs.com. At this decidedly family-oriented mountain, clans come to ski—together and separately, and in every sort of class, including ones for parents and kids. Families also come to join in the weekly fireworks, winter science program, and kids' night outs (during which kids eat dinner, watch movies, and decorate T-shirts—while their parents cut out). For pre-skiers, ages six weeks to three years old, a new day-care center opens this December with a staff of 20. And starting this season, even four- and five-year-olds can sign on for the snowboarding camp. For teens there's tree skiing, and two teen centers—no parents allowed.
