We are planning a trip to the area. The original plan was to stay in Breckenridge. We are 11 people, 1st time skiers (2 have once). Found out that one would like to try all three resorts, Breckenridge, Keystone, and Copper Mountain. Would Frisco be a good central location and would we be able to catch the shuttle here and not have to drive each day. We are flying into Denver and figure it might be cheaper to rent a van/car instead of shuttling from the airport. Any advice on that? Thank you?
