Thanks, guys.
We've never done the DDP since it's always just DH and myself, and we aren't that big eaters. But we got to thinking - what a bargain for kids at $10.99! We couldn't feed them on that for one day no matter where we ate. And DS and his wife love to have appetizers and dessert with meals, and this is their first time at WDW. So we think they'll be impressed, and we're really excited about it now too!
