I like the idea of having the option to attend the classes I want at camp, something for the novice, intermediate and advanced going on at the same time. I also like the idea of the same instructor working with a group twice during a camp, that way they can touch on the material a second time after that first class and expand on it the next class.
Camps should have some stuff that is not normally done in the school. Many of us work hard and save our money to attend these events and travel great distances to attend. We want something that is not normally done in our regular classes.
As for going to an event to push my self beyond my normal limits, I don't think so. If I travel 10 hours to go tot an event, I want a relaxed atmosphere with good training. If I want someone to push me on my warm ups, and basics for a couple days I'll stay home and work harder myself.
I have no problems paying for quality instruction, but i don't want to see someone screaming at a student to work harder after I have paid a lot of money and traveled for a day to get there. If a person wants that type of work out join the army they will pay you to accept it. Like many other people I view my time as valuable so I would rather spend it on a positive experience where I am learning all weekend in a relaxed atmosphere than push myself to exhaustion on my little bit of time off.
