I like the dance night idea a lot. I think the best way to make it a regular event would be to come up with some catchy name for it. Obviously alliteration works well here, ie: Topless Tuesdays. I'll bring spare panties for the ill prepared.
As a straightish guy active on achat I support hot kissing for WW. It's a very sensual pos that seemlessly links dancing, etc to more intense sexual pos's. Get it for women, and get it done pronto.
