We've used the
DDP 5 times now (once paid for, 4 other times free) and our favorite CS (best value?) are these:
MK-
Cosmic Rays-Chicken and Ribs-very sharable. My DM, DD9, and I have even shared it between the 3 of us.

Also
Pecos Bills-fixing bar-yum!
EPCOT-
Tangierine Cafe-DM and I shared Schwarma Platter-good and filling.
also, suprisingly,
Refreshment Port (McD's) by Canada. The day my DM and I shared the Schwarma platter I got my DD a meal there. She got the 9 piece McNuggets, large fries, large soda, and McFlurry for dessert. It was a lot of food.
Cantina San Angel-DM and I have shared the Plato Combinacion and it was plenty. Order DD a side of tortillas and everyone was happy!

(she made her own burrito and ate the churro dessert)
Sunshine Season- many choices. 1/2 chicken, salads, asian plate, etc. Our favorite is the rare tuna salad. Very good
DHS-we've eaten at
Pizza Planet but it's just okay. No other CS we've had there.
AK-
Flametree BBQ-again, a lot of good food.
Pizzafari is pretty good as well. Tuskers was the best but now it's buffet and a TS.
BB and TL-surprisingly both
Lottawatta Lodge and
Leaning Palms have some excellent, very sharable meals. The times when my DM and I haven't shared our meals, we've had food leftover. Surprisingly Lottawatta Lodge even has a Cobb Salad that is fresh, good, and large!
Resort-the food courts have a lot of good options. We don't use our CS for breakfast usually. Just eat something in the room or use a few SC for pastries. As we get towards the end of our trip if we have a lot of CS left, we will start eating breakfast at the food court.
This trip my DD will turn 10 so we will probably be ordering 2 adult meals for the 3 of us to share. It will be plenty. I should mention DD is not a big eater. If she was, this wouldn't work as well.
