I’m going. Ski is important but also good food and the experience there. Want to go some place with snow for a few days for the winter
are you going alone? with friends? family? kids? what terrain do you like to ski? when you want to go key to deciding Vail and Park City can get very crowded holidays and weekends. Aspen is further away and tends not to get day trippers. all three have great towns, food and ambience. have you considered Telluride?
