Having had a trial run at my niece's birthday last weekend, I think you're probably right.
Bouncy castle, 20 5 year old kids, what could go wrong?
Kye got loaded on sugar and punched my Brother in law in the nuts. Ryan went bat shit mental, but remembered to give his glasses to a responsible adult. Princess and Angel fell out over something, there were tears and Angel's mascara ran. Alex confused Billie for a girl, when it was a boy with hip length hair in a plait, wearing a combination of Real Madrid and Barca kit.
All soundtracked by comedy East Yorks accents, which my niece has now developed.
I had to pace my beer consumption.
