When we went in July, we were asked if we wanted charging privileges good throughout the parks during our stay. RPR had it divided into different increments....$100, $200, etc. We chose the $100 one just in case we decided on something big. The charge privilege was only activated on the adult room keys. I just looked at our room keys and there's nothing to identify them as such. I'm assuming that was for safety reasons. We would have had to show a credit card anyway in case they had to charge for any damages to the room, in-room bar use, etc. We had no problems with our credit card billing statement showing "accidental" charges from RPR.
