In the case of Loveland, you just have to contend with the snarl of traffic on I70. It's right before the Eisenhower tunnel, so it isn't as bad as Vail or Copper just up the road, but I70 traffic has gotten pretty brutal over the years. I've had routine 1 hour drives to/from a resort turn into 3-4+ hours more often than not.

Wolf Creek makes sense though - that's a bit more of a commitment. Your typical skier is probably going to be there for a few days and not just swinging up for a Saturday (at least coming from the front range.)
