So I'm at a new school this year and instead of having spring break in late February, it's gonna be around late March or early April. I know some Colorado ski resorts close around mid-April, but i was wondering if the skiing in early April is still good at that time of year or is it getting more warm/slushy. Would it would be better if I went after Christmas? We might be going to Vail or Beaver Creek or Keystone.
