2010 Update: The latest ski with a friend ticket prices are posted online at snow.com.
I spoke with a customer service representative at Vail Resorts today and was able to gather the following discounted ticket pricing (they’re called “Ski-With-A-Friend”, and each Colorado Pass holder can purchase up to 6 of these tickets).
Prices through February 15, 2008
The prices will go up slightly after 2/15 but the resorts won’t say how much yet. For more details call 888-215-3867.
Bonus: Found on the Colorado Pass bonus page, a little known fact: if you renewed your pass before May 31, 2007 (never known to me!) you are entitled to FOUR UNRESTRICTED $45 TICKETS valid all season at Vail, Beaver Creek, Breckenridge, Keystone and Arapahoe Basin.
