URGENT

It looks like our camping trip is going to be CANCELED! I'm really bummed but I don't know what to do. The other couple going has pulled out b/c the weather isn't looking so nice for Stone Mountain. Does anyone know of any place around here that has things to do? I need to find somewhere that we can take our kids and they won't be bored. I need a playground or something fun for both, Jessica and Darcy. We've invested way too much money in this trip to have it canceled!!!! My husband has taken off work, my FIL has taken off work to keep the boys on Friday and my parents are staying with the boys all weekend. I've gotta do something for them. Please I'm desperate... and i'm about to cry!!!!!!!!!!!!!!!!!!!!!
