I don't know how many times I been here throughout the past couple years, but xS is always a must visit on every trip for me out to Vegas.
Hand's down my favorite venue and possibly the most beautiful club in Las Vegas. If you aren't familiar with it, xS consists of an inside main room and also an outdoor patio/pool area. The venue itself is HUGE..easily fits in 1000s of people if you count the outside area.
Easiest way to get in is with BOTTLE SERVICE...haha no shit right? But it's true. Main room tables go easily in the 5k minimum range (depending on DJ talent) and tables are cheaper in the outside area. If your hosts tell you to arrive early MAKE SURE YOU DO, because xS sells out. So if you're getting a lower end table be sure to follow through with your host or else you're table will get sold and you'll have to grease your way into acquiring another table. I seen the bottle line be as long as general admission lines at other clubs sometimes.
Other then that, girls always get the easy entrance. But for my male counterparts out there, the easiest way to get in without dropping a couple grand for bottle service is with with presale tickets. You pay about half of the door cover price. Highly recomended if it's a big name DJ like Avicii, David Guetta, or Afrojack.
My favorite party in town is xS Sunday Night Swim. Nighttime pool party on Sunday nights in the summer. I always used to leave Vegas on Sunday until I discovered this party, now I always stay on Sunday nights! And don't look like a newbie, majority of people show up in dayclub attire!
If you're looking for less of a tourist crowd and less hassle to get into the club, Monday nights is xS industry nights. Bottle minimums are alot lower and its super easy to get inside.
I've never had a bad time here and i love partying at Wynn/Encore!
