In addition to the most snow in CO, we loved Wolf Creek for it's friendly staff, tasty and not expensive food, and that it's small enough to go with a group and see each other while you're out. It really has a small town feel to it.
Tip: If you are putting your child(ren) in ski school, you can keep your stuff there, and even bring a picnic lunch to eat there (rather than buying lockers). We loved hanging out there, even while our kids were in lessons, just to watch them from the windows and rest.
