Almost always a salad or app per person, an entree per person, and a dessert to split among two or three people. The dining plan offers about the same amount of food, with a few extra snack thrown in, which we tend not to want or use. The DxDP is way more food than we would normally eat so it is not for us.
That's the problem with the DDP... It offers the same amount of food, but not the way that your family would eat it. If you have 3 people in your party, you say you like to eat 3 apps, 3 entrees, and 1 dessert.
But the DDP would give you 3 entrees and 3 desserts. So you would be "wasting" 2 desserts, and would have to pay OOP for the salads/apps that you want.
So while the amount of food is the same, it's not actually the food that you would want.
That's why I find that the DDP really only works for a group of people who eat a very specific way. (Granted, there are lots of people in that group).
The DxDP could be for you, if you did a lot of signature restaurants, or changed you CS lunches to TS lunches. But yes, as you describe it, the DxDP would be overkill for you, and your most efficient $$$ is simply OOP.
