Came on a Saturday evening.  Got in line at 10:30pm or so with a group of 5 (3 guys, 2 girls) and got in within 15 minutes.  The line really does move fast!  So fast, in fact, one of our friends who had to run back to the room to drop something off (we were staying at the Encore) didn't make it back before we got in.\n\nWe all got the stamp and then headed back to our room for some drinking.  I waited in line with the 6th friend so she could get her stamp, just before 11pm at that point.  We moved through the line really quickly again, probably 10 minutes, got stamped and headed back to our room. Re-entry line is awesome. \n\nI think guys paid $30, but the girls and I were lucky to get passes for free.\n\nEven with a long line, the girls bathroom moves quickly too. Lots of stalls and ladies there to lead you to the next open stall. They are very efficient at XS!\n\nThe music was great and the dance floor was fantastic. Dancing essentially under the stars was a great experience.  I love the outdoor area, which is just brilliant.\n\nIf you're going to XS, just know what you're getting into and plan ahead. Do your research and don't be an idiot and show up at 1am, thinking you might not have to wait awhile.  People aren't going to be leaving the club that early, this is Vegas! Just commit to going to XS and get your dance on!
