The holidays are here. In Manhattan, many members of the tribe I study go away on a "winter break vacation." These vacations come in two varieties: ski and warm. Popular ski destinations include Aspen, Jackson Hole, Deer Valley, Sun Valley and St. Moritz. Popular Caribbean and warm weather winter break destinations include Anguilla, Turks & Caicos, Half Moon Resort in Jamaica and the One & Only Ocean Club in the Bahamas. If you are a glutton for punishment you might take your kids to Atlantis. Some people in the tribe I study do a "double" vacation over the winter or spring holiday — a week of warm weather vacation somewhere in the Caribbean and a week of skiing. Talk about over the top. Members of the tribe of Manhattan parents I study are currently packing, packing, packing and happy, happy, happy. At parties, everyone seems more relaxed and friendly than usual. But they're still also busy as can be. As any parent (let's get real, it's the mothers who do it) knows, it's not easy to pack yourself and your kids.
