Have you invited anyone who will dance, even if they are the only one? The hardest part is getting the first few people on the dance floor. After that, people usually feel more comfortable about dancing -- since they weren't the first or the only folks on the dance floor. Also, I've noticed that people are more ok about dancing if the lights aren't too bright (for several reasons!). Having some special lighting (disco ball, colored lights, or fog machine -- all can be rented) will also make the dance floor more appealing.

But, most of all is having some boys and girls that WILL dance, that WILL draw out others to dance with them. Not just the one couple who will dance but only with each other.

Good luck
