There is no age requirement to shoot at a range in Florida. Anyone under the age of 18 must be supervised meaning that while 1 child shoots an adult must watch and be able to physically take control of the firearm (and or child). To be clear, the adult can't even be holding another weapon. Each child will have their own day pass unless they are under the age of 16. I haven't seen a limit to the amount of children or size of family using day passes. In this case, call the desk to verify. Desk staff are always helpful.
In addition, any new shooter has to view a firearm safety video AND pass a test on it before being allowed to shoot. The previous information is also correct.
Sorry, I'm not sure of the rules when it comes to children.
