Ok, I got started, so will go ahead and share a bit more of what Lynn and I heard. I assume there are others on this forum with this same information, but they may have been required to sign formal non-disclosures, so don't expect them to say much. Unlike them, I don't have official or first-hand knowledge, just an interesting conversation in passing.
The "Premium Camps" won't be called PMTS, they will be branded and owned by Vail Resorts under license to HSS. They have an initial 20 current instructors at BC and 20 at Vail they plan to invite, with the intent to have 3 5-man teams at each resort ready for next year, but I'm unsure if any of those 40 have been contacted. I also believe that the plan is to compensate these "Premium Camp" instructors up to 30% more to jump start the transition, and in recognition of the time investment expected of the "Premium Camp" qualified staff. That's year one.
I think year 2 is where they plan to tighten and formalize lower parts of the ski school curriculum at Vail and BC while rolling out the Premium Camps to Heavenly and Breck, and I believe that the 'formal curriculum' revision is where the role of Epic Ski becomes apparent.
