The Mega Bounce will hold approx. 15-20 kids depending on the size of the children. This moonwalk gives you more bang for your buck allowing you to run through as many children as possible in the shortest amount of time. This unit has 1 blower that requires a regular 110V household outlet to operate. If you do not have power available, Fun Source rents generators to give you power but these are not included in the price of the unit.
