I used to snowboard on the cheap a lot. This was in 2006-2007, before I was married w/ kids, so I had time for this kind of stuff. The closest resort to me had a "night club card" program. They didn't sell it directly at the resort, you had to fill out a form through a club. They had a list of the clubs on their website, and my local high school was one of them. The night club card, if I remember correctly, was about $150, and I could ski any day of the week after 5 pm all season long, and after 1/1, starting at 3 on Sundays. It obviously isn't the same as a weekend experience, but the resort was close (ish) to my house and I ended up snowboarding 2-3 times a week for really not much money at all. And I had a regular day shift job and was busy most weekend traveling for my then-long-distance-boyfriend, so nights were the best time for me to snowboard, anyway. Maybe other resorts have similar programs?
