Face it ? 6-year-olds don't want expensive party favors or complicated theme parties for their birthdays. They want to jump around, drink soda and make a mess until the sugar high ends and they crash. And chances are, you probably don't want them doing this all over your house or expensive party decorations, so ditch the high-concept birthday and let them get that energy out at Pump It Up. True, it feels a little lazy, but there are advantages to letting the people at the "inflatable party zone" do the work for you: They do all the planning (they'll even preside over the gifts ? writing down the gift givers' names and bagging up the unwrapped gifts afterward), and you don't have to stress about coming up with a co-ed theme that won't make your kids feel awkward. The kids can bounce, slide and somersault to your choice of tunes, and afterward, pizza, drinks ? even goody bags ? are available, for an additional fee. Just bring your own cake.
