AAC Craggin' Classics - A good experience?

cragginclassic.com/#smith

So this looks pretty cool. I've never been to a climbing 'event'. I have some questions:

Has anyone been to a craggin' classic? Are they fun? Are they super packed with people? Have you been to them at smith before? How bad are the crowds?

What about the clinics? AAC has pretty much no information. How many people in a clinic? Are the clinics worth the money?

Any other information would be awesome, I'm interested in peoples experiences at Craggin Classics

Thanks!
