Thanks for all that. Never been before so all of that is super helpful. I ski at Big Bear and Mammoth currently so everything is gonna be epic to me. Is there a season pass that you would recommend for the best mountains?
The three main multi-mountains passes that I am aware of are:
1) Epic - Breck, Keystone, Vail, A-Basin, Beaver Creek
or Epic Local - Breck, Keystone, A-Basin + 10 days at Vail & Beaver Creek with restrictions during holidays
or Epic Summit County - Keystone & A-Basin with restrictions at Breck during holidays

2) Rocky Mountain Super Pass plus - Winter Park, Copper, Eldora + 6 days at Steamboat (holiday restrictions) and 3 days at Crested Butte (holiday restrictions)
or Rocky Mountains Super Pass regular - Winter Park and Copper only

3) Aspen/Snowmass - Unlimited at Aspen Mtn, Aspen Highlands, Buttermilk, and Snowmass

Now which one to choose... In my opinion, all mountains have their pros and cons. I'd check out the mountain stats/trail maps for each mountain, and then the main other aspect to consider is how busy each mountain will get - mountains closer to Denver/Front Range will be more busy.
