On the dining plan/Key to the World, it shows how many adults and children are in your group. On our last trip I tried to order 3 adult items somewhere at DS. We had 2 adults in my party and I was going to let the 2 kids share one adult item. They were tired of burgers and chicken fingers. When I ordered the lady wouldn't let me get 3 adult orders because my card showed that I only had 2 adults. But, I think if you order separately, such as 2 adults and then someone else orders adults for the kids, it wouldn't be a problem. I'd be interested to hear what others have to say about this option since I didn't try it.
