You would absolutely benefit! It's an opportunity to be exposed to a lot of things and practitioners of different levels and skills. There is plenty for the beginner to work on, as there is for the more advanced.
It's a great opportunity to meet many others who share your enthusiasm. And, if you stay at the practice long enough, you will look at the summer camps as a valuable part of your training and development.
I look forward to the camp each year, the training and the people. It's a highlight experience.
