I lived at the cosmopolitan, so I get in for free and I also get to line up at the hotel guest line which saved me so much time to get in. The marqee is packed. Music is decent, not my taste tho. If you are in vegas, and you live at the cosmopolitan, you should at least go to marqee, experience how's clubbing like in Vegas, make your trip worth it, even if you are not a clubbing person.
