Get season passes, and then you don't need to worry about it. Yeah its a bunch of money upfront, but if you buy in April or whenever they go on sale this year and pay it off over a couple months, you're golden. Snow is shit that day? Who cares, pack it in and go back tomorrow. Want to ski from 08:00 to 16:00? Have a blast. You just need to ski enough to make it worthwhile. I think my family and I had 24 visits this season, very much a great value for us.
