I am researching a possible 4-night 3-skiing days trip for me in that area, along with several other resorts for which I'll post separately. According to their bus system, they have transportation between Vail and Beaver Creek, but don't have transportation to Snowmass. Is Snowmass too far in another direction, and how far in case I decide to get a taxi? If it's too far, then I suppose I'll do 2 days at Vail and 1 at Beaver Creek.
Also, regarding lodging, the cheapest I found was Super 8 motel at Leadville, for $66/night which seems pretty low for the Vail surrounding, but I'd be willing to go even cheaper if anyone knows of anything else.
