if your kids are first time skiers, i suggest ski cooper just outside leadville. it takes just about under 3 hours from colorado springs with decent road conditions, via hwy 24. its a cheap mellow mountain, hardly ever a lift line, and usually has good snow. i was a liftie there for season, and family's that go there have a blast. but if you want fancy...go to breck or keystone.
monarch is good too, but can get over-crowded with texans
