Krabloonik is a good call, they have great wild game. You might give the Crystal Palace a try too, they have a good show.
Since Snowmass is the most crowed of the four mountains, get up and out of the village early. Lifts open at 8:30, but you can usually get on about 8:15. Head up to Big Burn and you will have an hour before anyone shows up. Then I would move to Alpine Springs and Elk Camp as it fills in. Sam’s Knob and Campground will be the lease crowded of all the lifts. They use to serve a great breakfast at Gwen's till 10:30, but I'm not sure they still do since she and George split.
Highlands is empty all the time and Aspen Mt. is only crowded at Chair 3 and the gondy from 10:30-12:00, the rest of the time its usually walk on. West Buttermilk just put in a high speed quad and you can park right at the base and have a nice picnic.
Don't worry about the snow just yet, it's still pretty early. You will have a good time!
