The other thing that causes wailing and queueing is face painting. It's great fun but save yourself time and money buy taking a pack of your own face paints, you can even let the kids paint each others faces! (Or yours!)
Last suggestion is flower garlands, we do buy and make them sometimes at festivals but they are very popular and worth taking a few with you.
