When paying OOP my DH and I shared a large pizza. You can get additional toppings, but they cost extra for each. We also shared the salad and got dessert. We had one slice left over. On the DDP each person must use 1 credit and can not share a credit. So if you wanted pizza you would have to order 2 individual pizzas. With salad and dessert, DH finishes his individual (4 slices) and I have a slice left over
