The grid in the center is the main hall, where the dancing is. To the south is the entrance, while the main hall is ringed by sidehalls that one can head into for some modicum of privacy. Heading off north and back are the back rooms. Around the main hall are the bars for serving beverages, of which there appear to be multiple. 

Veronica and Justine are facing off in the entrance.

Cindy and her entourage are at the side halls, to the bottom right.

Eden and her bullshit is nebulously far back.

Everyone else is nebulously in the main hall, unless otherwise stated. With this knowledge, hopefully one can more accurately place their characters in this cluster.
