Do I need an attendant? Yes ! There should ALWAYS be an adult to be in direct supervision of the inflatables at all times. The most important duties of an attendant are limiting the number of children in or on the inflatable at one time, making sure that the children are all of similar size and controlling the behavior of all participants. By following basic rules all children will be safe and have a great time. If you need someone to stay with the unit to supervise the kids. South Florida Bounce & Slide can provide an attendant for $20 per hour.
