Utah sucks. Don't expect a good nightlife and there are ugly girls here. Go to Vail.
Truth. That's why I'm going to CO this year.
In all seriousness, walk-to resorts are few and far between unless you're willing to pay serious $$$. Utah is great if you stay outside PC proper. Last time there we stayed in Sandy for dirt cheap in a 5BR townhouse, a stone's throw from Brighton, Solitude, Snowbird. Next to zero nightlife, though. Stayed in Breck a few years ago, fun little town and a good mountain with great parks. In Vail right now until Sunday and headed back to Breck next week. Tahoe has a ton of resorts but it's a bit like UT in that, you need a car to be able to travel around and hit different places. SLT is a super fun place to stay, and casinos are usually pretty reasonably priced as far as resort towns are concerned.
