They use metal detectors. Anything you wouldn't bring on a plane, you shouldn't bring in the park.
No sharp obejects, no pepper spray, no toy guns (even if the gun is bought at the park, once you leave it cant come back in) no selfie sticks, no costumes on children 14 and older.
I know selfie sticks are not allowed anymore. And children 14 and up to adult are not allowed in costume. Nothing sharp.
No selfie sticks
On my experience they didn't took anything on my bag, but it was only water, baby items that was all
