Marquee is in my opinion one of the best in Vegas as of right now. They always have great dj's headlining and there are several rooms to dance in. You can seriously get lost with all the stairs and rooms in Marquee! (WARNING: Drunkness will inhibit your sense of direction, especially at Marquee! Be ready to explore...)
The Library plays old school hip hop and has more of a relaxed vibe. Bottle service tables, fireplace, pool table and a bar. Upstairs from the main floor.
The Boombox is dance/hip hop mixes, very dark and gets VERY crowded. Has lots of tables inside, and direct access to the outside strip of balcony. Close to the elevators.
Main Stage is pretty small of an area to dance in, but if you go to see a DJ get your spot early! Bouncers close off the ramps once they feel it reaches capacity down there. They have awesome audio/visuals for DJ sets and one of my favorites is when it gets a little hot they blow puffs of cold air! Exactly what you need to keep your groove going!
Outdoors will play the same music as the DJ on the main stage just no special bells and whistles of course. But other times they have a DJ out there on a mini stage. Depends on the night
And as we all know, it will cost you your first born for a drink in Vegas, no surprise there. Drinks will be no less than $20!!
One thing is a plus is that they will offer free water! Unlike other clubs claim to only carry tiny bottled waters for $8!!! (AHEM, Haze)
Overall, a must in Vegas!
