I must say we were unsure if this was for real as we were approached by someone on the strip. They put us on the VIP guest list for Marquee with open bar for ladies before 11:30pm. I did not get the confirmation text right away but it finally came at around 6pm. Made it to Marquee at 10:20pm and we were able to skip the line and go straight upstairs. Make sure you ask for your wristband for the open bar, the Marquee staff "forgets"
Would definitely use again the next time we're in Vegas!
