Yeah, we went on a trip about 3 years ago with our 6 grandkids. Breakfast in room, Moms took care of that. I made pb &J or you could make your own deli sandwich , brought those and juice boxes into park. Many dinners back in the room. We ate maybe 4 CS meals in park and a few ice creams. But for the whole week, for 10 people , we paid roughly $1,000 for the week. Lot of work, but one of my memories is seeing all the kids crammed around the table eating dinner at disney. Of course the next min, it was kids bouncing off the walls, but we block those out.
We just thought with that many kids, it's faster to cook fish sticks and mac and cheese then trying to order 12 meals. And then the spilled drinks, dropped drum stick on ground, etc.
