For me, its an Eclipse err'damn weekend.
I come here almost weekly because I'm a fan of EDM and I like the chill atmosphere of pool parties.
Eclipse is definitely one of the smaller pool parties that are available in Las Vegas. But with that comes the benefit of less crowds (and, if its a holiday - its a holiday expect it to be busy). As always I recommend getting a cabana or a daybed/bottle service. You're going to enjoy it so much more.
I'm always here with a group so we usually get a daybed. The servers are sweethearts and for those of you who don't know procedure. TIP YOUR SERVERS!
Eclipse has several decent resident DJs including Krewella, and Nicky Romero. They used to have more djs but I think because its a smaller venue they didn't renew contracts. I could be wrong though.
If you're looking for something more chill and not as crowded as EBC, XS, or Wet come to Eclipse/Daylight.
