Damon will likely wind up there because bored vampires are sad, tragic things. But alcohol will be a draw, as well as partying and dancing. I'll likely have him drag along at least two of his loaned servants so he doesn't have to feed on anyone at the party, but hey, if someone wants to offer...

Mally will not be going =( Parties are for losers humans. Lame, guys.

Stiles might be talked into it if someone he knows is going.
