Sorry for being the 100000th person to post one of these "help me figure out where to go" threads, but here goes:
Looking to head west from ~5th-15th of March (dates I have off school) for my spring break with a couple of friends. For me it'll be my first time out west, and the group's skill ranges from intermediate to expert, with one beginner-intermediate kinda on the fence at this point. Probably the most important thing for the group is ease of access and terrain for a variety of skill levels. Being college students, the less $$ this takes out of the wallet the better, as well. And I haven't run this across the rest of the group, but I know that for at least two of us a relative lack of crowds also wouldn't hurt.
I like the idea of flying into Salt Lake City and doing some combination of Alta/Snowbird, PCMR, Canyons, Solitude, Brighton, etc., while on the other hand I'm intrigued by Copper and some other CO resorts. (Also had another group of friends with vast differences in skill do Aspen-Snowmass last year and absolutely loved it.) Big Sky, Whitefish, Sun Valley, etc. also seem to be awesome, although they seem to be either harder to get to (we'll be flying from Chicago) or substantially more expensive to get to, especially relative to the UT resorts.
I'd be happy to answer any other questions, and any help would really be appreciated, even if it's just a copy-paste of another useful thread (like I said, I know I'm far from the first to post one of these).
