I spend my weekends at my nice fairly non crowded mid-sized home, mountain, ragged. I go to the bigger places mid week only. I never wait more than a couple minutes to get back on the lift.
this is the way to go it you can. If I'm going to drop cash to go to sugarbush, stowe, BW or another random bigger place, I have zero interest in dealing with weekend crowds at those places.
Im lucky thought, my wife and I have awesome employers, we can actually use days off and bail on work mid week and bring the kids on a ski fever sick day off from school.
While I agree that weekday skiing is better than dealing with weekend crowds, one drawback of weekday skiing is that many of the larger resorts dont run all their lifts during the week making it much harder to lap certain areas, or even requiring hiking to get to certain areas midweek.
