For my wife and I, the
DDP is totally worth the price tag, both monetarily and mentally. On our honeymoon and one subsequent visit we had the standard plan and fell in love with the peace of mind that it offered in not having to watch every nickle and dime in our food costs, it was already paid for, and we factored into our budget as we paid off our resrvation over time. Not to mention that those table credits are super versatile, and some "snacks" are veirtual meals themselves.
Needless to say that with each trip we've found more ways to maximize the value, and had so many good experiences that we now opt for the Deluxe DDP for our trips. At @ about $200/day, they places, and food we eat are well worth it. We spend that much at a 2 point tabel for and still have anothet table service credit for our second meal for the day (usually a $100 tab). We usually use our snack credits for breakfast (those Gaston Cinnamon buns are pretty filling, and if at POR, begniets are a great value for breakfast. When you can basically recoupe the cost of one days points in one sitting and still get more food that day, big wim in my book.
On our last trip we had a couple of extra TS credits hanging out there, so we invited my parents, who live in the Winter Springs area, to have dinner with us at Toledo (a real treat for them). This really speaks to the versatility of the plan, let alone the amount of food available through it.
All that being said, I can see some instances where a family with younger children, can lose money if they opt for a Standard DDP, or now DDP+. If kids are picky eaters, and don't necessarily choose the most expensive item, or just opt for chicken tenders at every meal, you'd be lucky to break even in some cases. In those cases I recommend getting the QS option and mom and dad (or whichever, variation of couple) have their own date night out of pocket, at least once during the vacation (cuz it aint always about the kids).
It will be interesting on our anniversary trip this August, now than we have to budget for our food out of pocket, since Disney pulled the plug on our Delux DDP for the trip. We had some long awaited reservations we were looking forward to, not to mention review for my Chef's review thread. But it did open up anoter option that wasn't accepting the DDP, Takumi-Tei. Not looking forward to that credit card statment September.
