Ok, so this review is only based on one Monday night... but it was such a great night...\n\nMarquee Monday is where it's at. Girls in for free, and if you meet a promoter and have enough girls:guys, they'll get in free too. Open bar from 10-11pm. When we went, only one floor was open (the elevator man said there's usually 2 other floors?) but that one floor was plenty fun for me. It was a little dead at first, but our large group just had fun sitting outside enjoying the open bar. The dance floor started to pick up later on in the night, and there was about a 1 hour window where it was perfect - full, but not too crowded. Great DJ that night, and lots of interactive elements!! Occasional blasts of air, confetti dropping, tons of bubbles filling the dance floor, huge glow sticks everywhere, fun lights, etc. \n\nI had no sense of time while here, but there was that inevitable moment when the dance floor got so packed you literally could not move. I repeat, LITERALLY COULD NOT MOVE. It was horrible. But the place was so large there were plenty of other areas to peruse and hang out. Wish there were more places to sit, and yea drinks were expensive, but the $13-$15 well drink price seems pretty standard no matter where you go in Vegas. \n\nAt the end of the night, they were apparently passing out flip flops to the ladies!! What an ingenious idea!!
