Ask everyone to bring a dish they're famous for to pass. For soft drinks if you're offering, buy store brand. Much cheaper, or there's always store brand Kool- Aid type powder to make. If there are to be alcoholic beverages ask everyone to bring their favorite.
A volleyball game is always fun. If you don't have a net ask to borrow one. Check the net under cheap or low cost party ideas. You'll get some good ones.
Great GAL activity, Punkin! You can make it one they'll remember!
