I was the only woman who was gonna post to this thread who'd had more than one partner in a 24 hour period.   
 
The most in one 24 hour period was 11, I think.  It was a party where everyone knew everyone else fairly well, and most of the parties where these folks got together ended up in some sort of sexual free-for-all.  Over the course of several hours, I teamed up with four women and seven men.  Not all at once, though a couple of instances were two men and me, or a woman and a man and me....  I guess it was sort of orgyish...  It was lots of fun, though.  *grins*
I don't know if that one counts, exactly.....  it was just one single situation, rather than several unconnected liasons.... I think the most partners I've had in one 24 hour period who were unconnected liasons was 4.  *shrugs*  What can I say?  I was flirting with this guy I worked with and we nipped off to his car at lunch for a quick blow job, then after work, I fucked the owner of the company (I'd stayed late to do inventory).  I went home and took a shower, which my roommate joined me in....  *sighs with memory*  SHE was HOT....  lol....  We played around a while, then I went out.  I picked up a guy and a girl at the bar, but I went home with him (I think she was just playing around at trying women *shrugs*).  
I know, I know.  I was such a slut.
