Replying to Where to go in Colorado?

So for my spring break my family and i have tickets to and from colorado fro the first week of march. Now we have to decide where to stay for that week. We were looking at aspen/snowmass, breck, and vail. Anyother good suggestions would be appreciated with reasoning, also, even better, would be name of hotels that have decent deals or lift packages. Anyways, I am just looking for suggestions for where to go and places to stay, snowmass is the farthest we are willing to go from denver. thanks
