This place isn't really my "thing". I got in free because of CES (Consumer Electronics Show), otherwise cover for men was $30.
I suspect if nightclubs are your thing, Marquee is one of the best in Vegas. The dancers (pros paid by Marquee) are hot, the female customers are hot, and the dance floor is packed. The inside of the club is beautiful with lights syncrhonized to the music. There's an outdoor pool area as well.
It's just not my thing, but I don't slam places if I know I am obviously not their targeted audience.
