Doesn't UC Davis have a ski team? They did when my buddy was there. If you join, you probably pay about 400 dollars at the beginning of the year, which gives you access to a house in Tahoe for the whole season. Some weekends the house would have about 30 people living there, but that was part of the fun of it. I would definitely look into that.
I wen to the University of California in Santa Barbara. We had a ski team, similar to the one at Davis. We had a house in Mammoth each winter, and an early season pass was 600$. I would usually try to schedule tues-thurs classes for the winter quarter, which I was able to do. I would get one two day weekend, and one three day weekend, each month. Additionally, I would usually get 5-8 days of skiing xmas break, and another 5-8 spring break. It worked out to 30 days a year, about all of them at Mammoth. I knew other people who did even more, you just have to be willing to drive a lot.
I was a statistics major, so I had a lot of studying to do. It was about budgeting time, and getting those tues-thurs schedules for the winter. I was usually able to do that. Also, when you are doing 2 weekends a month the strain is not as bad as 3 days a week, so school is manageable.
If you want to ski 2-3 weekends a month UCSB/USC/UCLA/Berkeley/Davis/Stanford are all workable, due to the ski team situation. I know some people won't like to hear this, but I would rather ski Mammoth/Tahoe 5-6 days a month than anywhere in Vermont 8 days a month. If you want to ski 3 days a week, I would go somewhere like U of Utah.
