Grand Targhee Resorts
Skiing is not the cheapest, but Grand Targhee is cheaper than most, especially if you got yourself some year passes or other passes. You can stay the night in hotel room, that I will warn you now is old and a tad cold, and ski the next day and the next day. You can drive a few hours instead and not face a chilly-ish night, then ski for just the day. They have good snow and a verity of trails you can take: for beginners and for the more advance people. Plus not all trails are for skiing; they have tubing trails you can take if you aren't really a skier or a snowboarder. Whatever it is that you like to do in the winter, that has to do with skiing obviously, you can pretty much do it here http://www.grandtarghee.com/
