I just came back from Snowmass/Aspen. It was GREAT! I stayed at the Wildwood which is part of the Westin, so you can ski-in/ski-out to Snowmass, and catch the bus over to Aspen at the base of the village.
The Cirque was lots of fun (still some powder stashes in the trees, some steeps- think Mott canyon at Heavenly steep in some places), Long Shot is 3.5 miles and well worth the hike, and there's a steeper run that goes along the side of it. I was going to Highlands, but patrol said it was pretty icy and blown at the top so I ended up at Aspen today. It's kinda small and boring after spending an full day (9-3:30) on Snowmass, but you can blast around on the groomers there and pop off the rollers.
I'd need to look at a map to give you specifics, but I can say you will not be disappointed in Snowmass. Aspen was fun for the grooms and has a better apres scene.
