We're hosting my three year old son's birthday party next weekend at a local gymnastics place. It's an hour in the gym, and then an hour in the party room. When we had my older son's birthday there it was a bit dicey, because as soon as pizza was over the kids wanted to go back into the gym, but they don't get to - there's already another group of kids in there. So this time we'd like to learn a lesson and have some games/activities going on to keep them entertained.

It's a superhero theme, and so far I'm thinking of bringing some music to play freeze dance, I bought some paddle ball games for colouring, and am going to print out some printables for more colouring. We'll also obviously have pizza and cake. My husband is way out in left field going "Let's bring the costume rack and have a dress up corner!" - he seems to think we're setting up a daycare. But is there anything easy and cheap that I'm not thinking of? I had thought about those "decorate your own mask" kits but we're giving capes and masks in the treat bag, and I thought of some kind of "pin the mask on Batman" thing but don't really want to get into a situation where I'm giving out prizes.
