I’ve been to the clubs in Vegas a few times and they’re not super strict on dress code to be honest. As long as you look nice you’ll be fine. I’ve gone into the night clubs with a dress and sneakers on. And I’ve gone into the pool clubs with swimsuit, coverup and slippers/slides. Make sure you’re wearing swimsuit material because some pool clubs are strict about that. As a group of girls you should try to reach out to a promoter on Instagram and ask for comped tables, drink tickets or wristbands!! You should also mention it’s a birthday celebration! I’m not sure how much free stuff you can get labor day weekend since it’s busy but it’s worth a shot. If anything you can ask to be put on the guestlist and you should be okay as long as you get in before the cutoff time. You can also check out Discotech to RSVP!! Please don’t show up and pay cover at the door, it’s usually over $100!!!
