Unfortunately I couldn't attend this class because we had games in buffalo that weekend. But I heard some great things about Dan's lesson. Dan did Zumba and I heard his routine was pristine and he was very energetic and motivating.
One of the issues Dan faced was that he had a blind student in his class. All of his cues and direction was visual based so he had quite an issue in his hands. But he got through it okay and we learned a valuable lesson to be prepared for anything.
