Hmmm. Sounds kind of like the "Sugarwood" Pass they used to have in Tahoe that was for Sugarbowl and Kirkwood, two resorts that to the best of my knowledge aren't owned by the same folks.
And I like Old School. I grew up skiing Sugarbowl (my dad was a weekend Ski Patrol there in the '60s and '70s) and have an affinity for Alpine Meadows and Homewood, both of which feel Old School to me in terms of Tahoe.
Love Alta, as well, out of the 3 Utah resorts I've been too, because of it's O.G. vibe.
Sadly, I've only been to Keystone, Copper, Breck, Vail, and BC in Colo. Like the vibe at Keystone best and have had some great skiing off of Peaks 7/8 at Breck. I can do w/o Vail and need to hit BC on a good day (the time we skied there 2 seasons ago it was cold as ice, stormy, and there was lots of ice and wind...i'd give it another crack, though).
