I went to a private party at VANITY and it's a pretty good venue.
I don't know what this place is like if/when it's open to the general public.
There's 2 bars and a decent sized dance floor, so it's a good venue should any corporate entity decide to invite guests and throw a private party in Vegas.
Like anything else, the party is only as good as the guests.
So, I'm not sure what type of clientele comes to Vanity.
However, if you're bringing in your own crew and it's invitation only, this is a worthy place to host a party.
