For your large family, you'll spend $35-50 for a meal at the food court.
On our very first trip to WDW, we decided that we don't like the food courts. They're expensive, but the food really isn't good. We'd just as soon have sandwiches in the room -- same quality, lower price. We might grab milk or an ice cream bar from the food court, but we don't plan meals there.
We feel like we're scrimping on these quicky-meals at the hotel so that we can afford to splurge on really good meals at other unique Disney restaurants.
