I didn't even know about the Flowers Plantation camp and I live right near there.
Here are a few more in Clayton;

Kids Clubhouse:
Kid's Clubhouse : Summer Camp : Field Trips : Clayton : Garner : 4042 : Cleveland (http://www.kids-clubhouse.us/summer_camp.shtml - broken link)
Interskate:

We've done Riverwood. It was good, kids loved it. Swimming at Riverwood daily. The interskate camp looks REALLY good.
That's all I can think of at the moment but I'm sure there are a couple more.

PS...there's also screaming mimis in a pinch. I had to use them last summer but it was a bit boring for the kids since its all indoors although they've just announced that is changing or they are adding trips or something.
