How much does your family eat? From the amount the OP quoted, 194.95/day, every member of the family is being charged the adult price. The DDP is a lot of food, and that alone may be worth it for some families. If you are all big eaters, or DH and two teenage sons can pack it away, even if mom and DD14 eat salads and want to share an appetizer for their main course (sorry, I know that's a stereotype, but it's just an example), it can still be a great savings. I have three boys, and they all went through a stage where they ate like horses (the youngest is just now entering that stage

) If you are all light eaters, or your 11 and 14 year old DD are barely in the "adult" price category and would still prefer the kids' menu selections and portions, then it could be a huge waste of money. A dinner table groaning under the weight of 5 appetizers, 5 entrees, and 5 desserts would just be ridiculous for your family.
Does your family prefer to share, especially appetizers and large entrees? That can work well and save money, but does everyone have similar tastes? If one person loves seafood, another loves steak, one kid is super picky, and another is a vegetarian...sharing probably won't be all that successful. If everyone likes the same thing, it can work beautifully.
Do you have a fridge in your room, or are you willing to keep a cooler for snacks and breakfast foods? And are you willing to serve and clean up breakfast every morning (even just bowls of cold cereal or muffins and juice)? It saves money, and we certainly have done that when the boys were younger and the budget was tight. But now, I just don't wanna do it -- too much like I'm
not on vacation.
Does your family normally eat only CS on vacation, and wants to go, go, go at the parks? If you don't like to sit down for a TS meal every day, the DDP is a bust.
Do you like buffets and/or character meals? No matter how much or how little your family members eat, every buffet or CM is the exact same price for each person 10 and over. The cost of one buffet per day can be almost worth the price of the plan.
When you do order TS, do you typically order the cheapest menu items, even if it's not what you really want? Or would you really rather have a nice steak or seafood entree? If you order one $25 entree, $3 drink, with tax and tip it's about $35 -- that's not including appetizer, dessert, the CS meal (which is worth another $8-$15), and the snack credit. If we are paying OOP we tend to compromise and look for cheaper menu items to make our food budget go further, but it's not always what we
really want to order.
As others have mentioned --
do you want to go offsite for food? You can...but you will have to drive there, which takes away from park time. We won't have a car and don't know Orlando, so it's much more convenient to eat at the Disney restaurants anyway.
Is "theme dining" an important part of your vacation experience? Again, as others have mentioned, I can eat at Chili's or McDonald's any day. I can't always have breakfast with Stitch, or Snow White and Ariel. I can't always slurp a shake in a vintage car under the stars at a drive-in, watching a cheesy Sci Fi movie. I can't always attend a luau or a hoedown. And where else can I eat a snack in Morocco, France, Germany, Japan, and Norway all in the same day?

For many guests, Disney dining is part of the "entertainment" budget on their vacation.
The DDP certainly doesn't work for every family, but for others, it really is a very good deal
