They can go on the rides by themselves if the are taller than 54 inches. But I wouldn't leave them alone in the park by themselves. You can enter the park without having to pay, you just can't go on the rides.
It goes by height requirements if they can ride alone. Most rides, if over 54 inches they can ride without parent.
I don't think would be good idea kids by themselves they should be under parents supervision
Signs say must be accompanied by adult It's not a good idea to drop teens off their.
It all depends in the height requirements for each ride!
