We love your kids—we really do. But we want our night to be fun for YOU! If you're good at wrangling your little one, bring them to enjoy the fun, but understand that if you do, the risks assumed are all on you! In other words, if your kiddos won't keep you or other guests from enjoying themselves they're welcome but understand there's a pool and other potential dangers at the venue so if you bring them, make sure to keep them close as no one will be assigned to keep an eye on them - you bring them at your own risk.
If your invitation says "and guest," then, yes! If not, we'd prefer if it was just you.
Dressy casual. Like what you'd wear for a night out with a nice dinner and drinks. BUT...we also want you to be comfortable enough to have a good time, so if those shoes are too high or that top button is too tight, let it all hang loose! We're all friends here!
