I've been 4 times. The last time I went, it was with my friend Cindi, and we both signed up for classes with Danny Amazonas and Yoko Saito. Thought for sure we would not get into the classes, especially Yoko, because she only had 20 spots available. But to our amazement and delight, we both got in! And the classes were AWESOME!!!
Get the class catalog, figure out what classes you want to take, and sign up as soon as registration opens. You never know!
