If you're going to ski more than about 6 days at any of the Vail Resorts (Vail, BC, Keystone, Breck) plus Arapahoe Basin it is worth it to just buy a season pass. The Epic Pass was $579 this year and includes Heavenly, plus unlimited access and no blackouts at the other 5 resorts. The Colorado pass is unlimited at Keystone, Breck and the Basin plus you get 10 days at Vail or Beaver and is about 100$ cheaper depending on when you buy it. Having the pass will then allow you to buy discount tix for the rest of your family, plus you'll get emails about discounted lodging and food and what not.

Also, a month or so ago Skiing magazine had an article on 'recession proof' skiing, basically great deals around the country at different resorts.

Now someone get out to Tahoe and tell me how bottomless it is right now!
