would suggest what ever the season pass is for keystone and abasin..they are open first and close last..best bang for the buck if you plan to ski 3 or more days...i think the season pass is like 400 something and the 3 day tickets is like 370 something.....abasin will fore sure be open with some stuff...but expect some lines, there is a cities worth of skiers cramming into maybe 6 lift lines across the county that early in november...it is brutal...but keystone is opening super early this year so it shouldn't be too bad
