I go to regular Zumba 3 times a week at $5/time which is the going rate in my area. I absolutely LOVE Zumba! I have a Zumba for the Wii and I never use it as I get more out of actually going. I have heard that Zumba Gold is less hard on knees and feet. I think you should give it a try...at least for the 7 classes you would need to commit to. I think you will find you enjoy it.
