Wow, I am jealous. I only went to a JazzerJam in Columbus, Ohio. We did a dance routine on stage. Shanna, Judy's daughter was there and I thought that was BIG stuff.
It is really motivating but you are right, the instructor DOES make all the difference. Luckily, we have 5 great ones. I like them all and they each have their own style.
Our Main instuctor asked me years ago to try out, at the time I owned a salon and didn't have time. I just wonder what kind of shape I would be in NOW if I would have!!! Still don't think I could talk and guide while thinking of the next steps coming up. I am amazed at how they do that.
