You'll love the Rockies! So many outdoor things to do all year. The big ski resorts I can think of with my opinions:
Vail : The best, back bowls are amazing! Snooty people, a little farther away
Aspen : Haven't been, even farther away
Beaver Creek : Close to Vail, also nice but not quite as good
Breckenridge : Pretty good and cheaper, but very crowded every time I've been
Keystone : Best bang for your buck that I've been to, fairly large area with small crowds
A-Basin : Small, slow lifts, but open the longest. Probably not a good place to learn
Loveland : Never been, but looks similar to A-Basin
Copper Mtn : Pretty nice, only been one day
Winter Park : Never been
Steamboat Springs : Never been, but supposed to be nice
This last season I got a 5 mtn pass (Vail, Beaver Creek, Breck, Keyston, A-Basin) for about $400. They also sell 4-packs to Keystone/A-Basin for about $100. Yes, it's an expensive pastime. You also have to figure in the cost of clothes, rentals, and gas. My advice : bring your lunch.
