It depends on the weather and the tires.
I drove a minivan for 11 years in Anchorage. Usually I'd have studded tires on all four wheels during the winter.
Now I'm in Boise and I have old all season tires on my current minivan with not much tread left. We had 3 inches yesterday and I had to wait for most of it to melt to get up my long, slightly steep driveway. But it did fine on the main roads, even with the old tires.
Sugar today is relatively warm, running between 38 and 58 degrees. I'd think the roads would be pretty good at those temps unless you hit some storms.
I'd be happy driving a minivan, but you may want to pick up a bag of kitty litter on the way to the ski hill. And try to find a level spot to park in the parking lot; seems like that's where I always get stuck.
