Planning on skiing for a few days, and tips or pointers? What about night-life?

Hit up Main Street and party down. I lived there for 4+ years and am lucky to still be alive. Ski The Canyons or better yet take a day trip to Snowbasin. Sick stuff indeed.

Harry-Os and Suede have good music in town. Ask for a sponsor instead of buying a temp membership if you go to any club (crazy blue laws).

If you go in to Salt Lake for dinner I'd reccommend Martine or Cucina Toscana.

Ski/board at the Canyons if you get a chance. Snowbird is my favorite, but if you are staying in Park City then you'll probably hit the slopes there as well.
