Don't know about jewelry but you cannot bring any cooler like even foam cooler inside.
It is best to leave it at home if it is not tight on n you.
Me personally i wouldnt risk losing anything i leave everything at home or in my car
For vanish point I had a necklace and earrings on. I also saw people with sunglasses and shoes, they just had to hold them in thier hands. I dont think youll have any issues on the other slides.
