Atlantis Aquaventure / Waterpark Sunglasses/Hats/Cameras + Lockers

I just booked a day pass for Atlantis and am so excited! It seems you cannot wear sunglasses without a strap on the actual slides but I was wondering if hats are okay, waterproof cameras, and also a waterproof phone case that goes around your neck. Not sure if I want to bring these items or not so first of all, are they allowed on the slides?

Also does anyone have up to date locker pricing?

Thanks!

I didn't try to take any of those things on slides when I went to Aquaventure, but my guess would be definitely not on the thrill slides. Living in Orlando and going to many water parks, I can't think of any big water slide where hats or cameras would be allowed. (Not that people haven't done it, I'm sure there are youtube videos of slides done with GoPros)
