Hi, Daphne!
I took a tour of Disney's Art of Animation Resort this past June and I can tell you that this resort is AWESOME!
First of all, the pools are phenomenal; secondly, the food court, Landscape of Flavors, is divine. I am not even exaggerating. (Seriously. Yum!) The rooms, too, are exceptionally nice, and would surely make your children smile each time they enter it.
With three children, though, you might want to check out a Suite in a different section of this fabulous resort. Little Mermaid Standard Rooms are designed to accommodate 4, not five, so if you need to sleep 5, a
Disney's Art of Animation Family Suite might be a better fit for your family.
Either way, I know that your gang will LOVE this resort! Please send more questions as you think of them, Daphne; I'd love to help!
