I think this is a case of good idea, bad execution. When I saw those small pads, I winced instinctively.
All they'd really need to do is come up with some sort of overall sponge pad. For smaller kids, just catching an extra inch of air, or the sensation of being able to do so, would be enough.
Heck, my kids Tigger-bounce anywhere, anyway--so this could be largely illusory--just a space dedicated to bouncing, and they'd probably go nuts and have a great time. Disney needs places where kids can just blow off some energy.
So--they could vastly simplify this, even put in some sort of light beam sensor that plays a "boing" sound when broken, and the kids would have a great time, and never know that it's actually very simple, and very safe.
So hopefully they can go this, because the idea is good.
