From a post of mine a couple of years ago...

"I think that a lot of you are missing the point of this clinic. I took it two years ago and it was excellent. When we got there, they separated people into two groups. Basically it was a group of us in our fifties and another group in their sixties/seventies. A lot of the folks that took the class weren't the most athletic folks, so the idea of teaching them a way to negotiate the bumps without torching their legs for the day was pretty appealing. The student to instructor ratio was really low; either 3:1 or 2:1 depending if Joe spent the morning/afternoon with your class. As noted above, one of the main techniques that was taught was the pivot slip - or as the instructors called it "drift". The idea was that you're not using a ton of energy bending your knees all of the time. You "drift" from bump to bump. This was really appealing if you have knee issues or typically aren't in the best shape. Not everyone is a hyper fit, master skier. A lot of other ground was covered in the clinic, not just bumps. I learned a lot about turn initiation, ankle flexion, looking where you are going to plan for the next turn, etc. Yeah, I know, all of this stuff is covered in "regular" ski lessons. Putting it all together with the bumps instruction really made it come together. Just my opinion.
Oh yeah, if you get Alan Bush as your instructor, you hit the jackpot."
And as far as Killington bumps vs Aspen bumps? Do you want to ski rock hard, icy moguls or soft, high altitude West Coast moguls. Something else to think about.
