Man this thread is weird to me. I don't think I understand humans.
I've been to a lot of these Vegas clubs, including just about all of the ones mentioned, but only for corporate buyouts/open bars, so didn't pay anything. I have no clue why anyone would pay extra for one over the other, let alone pay these prices. All of the alcohol is the same, the loud music is roughly the same, and they only really vary in their gimmicky decor. One has shiny objects, another has a nice strip view, infinity pools, an elaborate stage, whatever. The only thing that made one better (or even different) from any other is if they had a good band playing, which doesn't have anything to do with the venue.
I get the idea of dropping some cash to have fun, but who finds it fun to pay for the privilege to play pretend VIP? I could maybe see that if you were actually fooling anybody, but it's Vegas. Everybody in the club knows you aren't shit there, don't they?
Then again, I don't get the instagram thing either.
Also, girls work the casino floors at the high end places if you want that. Better ones than will fall for some pretend VIP game, and it wont even cost as much.
