It's also worth noting the RMSP+ (Copper/Winter Park/Steamboat + 3 days at Monarch) is a much better powder chasing pass. It is far much more geographically spread out to catch different storms, and the areas are not nearly as crowded so they don't get tracked up as quickly.
The Epic Pass areas (Vail/Beaver Creek/Breck/Keystone/A-basin) are much closer together geographically and are more crowded on a skier visit/acre basis. Might as well take a Epic vs. RMSP tangent
RMSP+ + A-Basin for late April to May+ = not much >$$$ than Epic.
Look at all those pluses.
