Leila Haddad Leila Haddad does a weeklong workshop in Marrakesh, July 6-13, that coincides with the national folklore festival.
If you are in a big city, you can try to see if one of the gyms has any dance classes, but, in my experience, it takes a LOT of time to track down this information and you won't necessarily want to spend your days doing that. Instruction is usually very, um, unstructured - follow the bouncing butt.
I hope you can get yourself invited to a wedding or something to see (and participate) in the dancing. Have fun!
