Most party guests would happily eat chips straight from the bag in a joyful, relaxed atmosphere than be served caviar and champagne at a party with no umph.
Most parents would rather gnaw off their own arms than face the daunting task of hosting a kids’ party. Hence the trend to outsource parties to playcentres or indoor amusement facilities. I’ve done it. Were the parties successful? Sure. Were they especially memorable? Not particularly. Were they expensive? Absolutely. Throw in food and loot bags (don't even get me started) and these affairs can cost a (gnawed) arm and a leg.
