Just wanted to know your views on Zumba Fitness?

It's pretty popular in Brisbane at the moment (well, in my area), and I'm thinking of trying it. There's a few local instructors that are having an event in my area (Redlands) on the school holidays. They're advertising that the whole family can go so I guess it would be a good reason to try it... bring my daughter along.

What are your experiences? Would you go to the event? Or is it a waste of time?
