The calendar for this season is posted on the CT Ski Counsel web site. There is never a weekend without a deal, Saturday and Sunday, even holidays that would normally be blacked out with a regular resort pass. Lots of weekdays, but not all. If you like variety, it's a great option. Personally, I get sick of riding the same place all the time.
Man, seriously - thank you so much for this suggestion. Even if I get the season pass, this is still a great option for other resorts. I agree, I do tire of riding the same place but Stowe is pretty big mountain and I have yet to get bored with it. Hmmmmmmmmm.
