We were around 5000-6000 including airfare for 2 adults, 3 children (DS1 was juuuust under turning 10). We stayed at a moderate (POR), and were booked during Stay, Play, Dine, which gave a discount on room, tickets, and food. We were there Feb 3-10th. We did the dining plan, but only because with S,P,D it was an okay deal. In the future, I would strongly consider skipping the meal plan unless we were there during a significant promotion. It is just so. much. food. My kids didn't want any more sugar, snacks, whatever by the last 2 days. At all. And we easily could have shared many, many, many of our meals without anyone feeling the least bit slighted. Our travel agent upgraded my two oldest kids to adult dining, which was not an issue since during S,P,D adults could get the dining plan for kid prices IIRC. That was nice as they enjoyed eating from the adult menu offerings.
