<So that to avoid kidnapping - you could make a way that a kid can just go out with his parent or the person he came in with. Maybe security at the entrance - congestrons when clossing maybe? Look like "jail"? People may not like it?>
We don't want parent to leave his child on our new play place. They will come to this new public space in order to play together. Parent won’t leave his kid alone. Moreover this place will be public and very open space visible from everywhere. There won’t be dark corners. It has to be very clear and safe place. All this attributes should avoid dangerous cases like kidnapping, pickpockets and any other threats.
