Depending on the party, I definitely have people that would go! Porphyria Dempsey would be especially nosy about a vampire in society.

He and Ishmael obviously live fairly different lives but they should def meet and/or could have bumped into each before other in past decades or so, Ishmael's been all over the place in his time. He also likes to think he knows all the vampire stuff going on in the country... and he wouldn't say not to party invites plskthnx.xD

Barnaby Wye is obvs not a vampire, but is Also Old, they could be funny.
