Thanks for the tips. Called the Vail ticket office and if I go for the two day pass from the Vail website and not the Breck website, I can use it at both places regardless of day - this gives me flexibility depending on what the weather is doing.
The Breck two day pass won't work at Vail or Beaver Creek. However the Vail 2 day is good at all five Epic locations. Good for 2 out of 3 days days.
Perfect. Thanks for the advice to call.
