I cant help but vouch for the camp.
The focus on both a traditional and contemporary style of debate (if that's what you wanted) was probably the best aspect of HOA. That and the insanely low cost. Ziegler was dead on when he said that the camp is extremely useful in learning how to adapt to different styles of judging. Going into the camp, my problem was my inability to adapt to traditional judging. I had experience almost exclusively with "champ" styles of debate and wasnt sure how to handle a judged that wanted a slower, less critical round. HOA made sure that this wasn't ever going to be a problem again. And it worked.
Definately a great camp, worth tons more than you're being asked to pay
