Telluride is a very cool spot, I spent a week there around New Years last season. I didn't see a single flake of snow until the day I left, but there was still enough acreage to keep me entertained. I would have to say that the mountain itself is better for skiers though, there are lots of flat spots mid-mountain that can be difficult for the boarders to get through. Lift tickets there were probably more expensive than anywhere else I've been, hopefully if you're getting some kind of group thing you won't get hit quite as hard as I did.
Check out Silverton too if you're into freeriding, though it's not your typical modern resort and you have to get a guide after a certain point in the season.
