Just from reading it's apparent that Breck is addressing scheduling issues (ie not knowing what days and how many will show up) and maxing out the groups to make efficient use of the instructors since it doesn't appear these groups are being led by low level pros. The no Sunday thing is probably to have those instructors available for the normal, higher cost lessons which more likely occur on the weekend.
So here's the thing. No one is arguing that this isn't still a great deal. No one is arguing that your points don't make sense. But don't send me an email about how incredibly awesome and customer-centric this new setup is when that's clearly not why you did it. It's insulting. And so very corporate, when the lesson club was the one thing about Breck that didn't feel that way.
They're tearing the fabric of a community that they built. That's sad, even if it makes sense from the company's perspective. I've met tens if not hundreds of potential ski buddies through this system, and I've free skied with a number of them. I'll miss the community.
