Cascade has 36 ski runs of varying difficulty and snow tubing, too. Half-day learning programs for kids ages 4-12 are available. Because this is a bit of a drive from Chicago, ask about Cascade's lodging packages at the near-by Wisconsin Dells. You might get to go skiing and use the indoor water parks all in one weekend. The mountain will be open Thanksgiving through March, depending on snow conditions.
