We recently stayed at the Cosmopolitan (for my friend's bachelorette party) and decided to check out the nightclub downstairs. It was very nice, because the group of us girls got in to Marquee for free & without much of a wait (5 minutes at most), since we were staying at the hotel and a friend of ours also had put us on the guest list. We had a fun time at the club, but the indoor dance area gets PACKED!! It doesn't have as much space as some of the other nightclubs I've been to in Vegas, like XS (which has tons of outdoor and indoor space). We did like the patio area, where they were playing live music. I enjoyed the view of the Strip from up there, as well as the nice lights and eclectic water fountain / pool thing they had going on. We didn't get any drinks (pre-party up in the room!) but had a decent time standing around and swaying. Now that I'm engaged (and in my mid-to-late 20s), clubs aren't all that interesting to me anymore, but we had a great time with the bachelorette! Definitely a fun club, and I would have LOVED it more if I was 21/22 ;)
