I did one of the traveling camps about 10 years ago. At the time I was averaging 190-195 and I felt it was worth it. Yeah, you have to do some basics, but that never hurt anyone. I also felt the coaches were good at working on more advanced stuff with the better bowlers.
You do a lot of drills. They don't even put pins out until like the last day. You will work on your release, footwork, weight transfer. They will videotape you before and after so you can see anything they've changed. If you don't have a spare shooting system, they will teach you one. If you already have one, they will tweak it if needed.
If I had the time and money I'd do it again.
