A ski and stay package can be a good way to enjoy the slopes and save. Killington, for example, has 2 - 7 day packages that include lodging, lift tickets, and a ski or snowboarding lessons. Hunter Mountain's Stay and Play packages start at $89/night for a mid-week visit. Jiminy Peak has packages that include lift tickets, a discounted second night, and kids stay free.
If you have a ski resort you're planning on visiting, check to see if the web site has a Specials or Packages section. Also, check with Expedia or Travelocity - they often have package deals, as well. If you're flexiblity as to dates (mid-week packages are bountiful), you'll get the best savings.
