Latin American Dances?

Hello Folks, I am a caller in Minnesota, and I also happen to be a Spanish teacher. I am embarrassed to say that I don't teach dance to my students. Does anyone have any great resources that they would recommend that would help me delve into the world of Latin American dance? I am aware that traditional dance varies quite a bit regionally, but I'm willing to start anywhere that's accessible and fun to do in a mixed group!
