We (2 adults, 2 kids) paid for the DDP one time; back when the plan included appetizers for each person, and it was more food than we could enjoy. We've found that we could pay OOP for all the food we wanted and spend hundreds of dollars less for food during a week long vacation than the DDP costs. No, we did not eat a TS meal every day, but unless you were going to eat more than at least one TS meal for each day, you are pretty much guaranteed to spend more money purchasing the dining plan. Disney knows this of course, and that's why they promote it so heavily. It may be convenient, but it is not a money saver.
