Hey guys, I have been trying to work out the dance floor for some time now cause I usually suck at it. Here is some things I have tried that have worked on a half full dance floor where there is enough space to take a few steps here and there, not shoulder to shoulder.
This should be done assuming you are following the beat and create a larger then life dance style by overemphaisiing your dance mooves. All with confidence.
Dance moove one. Confidently, walk up to a girl as you are about to start dancing with her. Have a smile, keep eye contact, dance with your shoulders or whatever type of dance moove that gives her the cues that you going to be really fun to dance with. Wait till you get about a foot away from her. Bang\!! Turn around and slowly dance away from her. If she is keen she WILL follow. Cat and mouse.
Dance moove two. (I had three red bulls when i tried this so I was getting funky) When your dancing, point at a girl that will be either close to you or walking by, and as you do this make circles in the air, getting smaller and closer to her each time (Like the hypnotist wheel). This will steal her attention. Next moving your fingers continually but keeping your hand in the same place, slowly signal her to moove in towards you, bringing you hand hack as you do this. From here you can either take her hands and start shaking like a crazy latino, or just start grinding up against her.
Another thing I do on the dance floor when I am initaitng a dance with a target, or am trying to escelating kino is stand side on to them and bump my hip into theirs, as a dance moove. I do this about three or four times untill they respond. They usually do respond the first time but some of them are slow for some reason, never had a negative reaciton from this. After this she will initate kino back by bumping you back. You keep it going for a while and they will always laugh and think its fun. From here you can neg their dancing or just grind up against them from behind, gradually going from the side on to front on, or whatever you wish to improvise with to contoinue the escelation.

This is all stuff that has worked for me over the past three weeks.
