The first thing to say about XS: the place is gorgeous. It is one of the largest nightclubs I have ever seen and the decor is amazing. The patio is what makes the place so great but it was freezing when I was there right after New Years so I didn't really get to experience it.
I had gone right when the club opened (10pm) but the place filled up really fast! I was pretty surprised but then again, XS is one of the hottest clubs in Vegas right now.
The dancefloor was empty for a bit but also filled up pretty fast and about half an hour after dancing a bit, some awesome high roller at a table started making it rain onto the dancefloor! Ok so it was only $1 bills but I made $36! He totally made my night. After the rain, everyone packed onto the dancefloor and the music got better so everything was awesome!
The one thing about XS that I didn't like was that the bouncer that we talked to didn't know our promoter even though one of the other bouncers knew him. She wanted us to go to the back of the line and get a ticket and it was just so complicated. I was just annoyed because another bouncer had clearly recognized the name of our promoter but we had to pay extra to get in because this other woman didn't know him. Girls got in for free but guys had to pay the $30 cover. LAME. Make sure all the bouncers know your promoter!
But it's no big deal because I made $36 anyway :)
