I used the DDP back when it first came into being....great deal back then. Then, they took the gratuities out, and raised the price...used it once. Then, I got
free dining (stayed at Pop to do that and it saved me about $150 since it was just me traveling).
I own DVC, and always have an AP..so I like to get the TiW card. That seems to work better for us.
But, having said that.....when my dh and I traveled to WDW in Oct, with another couple, we decided to go with the deluxe dining plan. I sat, for hours, running figures every which way, to see what was the best deal for us. Since we decided to do a lot of signature dining, the deluxe plan worked very well. And it saved us money. We had a 2TS meal at night, and a late breakfast for 1TS each day.....seldom used snack credits. In fact, we bought a ton of stuff on our last day in order to use them up, and took the stuff home with us and handed it out to our kids!!
Now that the cost is over $50 a day, per adult?? Disney keeps raising food prices....not sure if that's to cover the cost of the DDP, or the DDP is going up to keep up with the increased food costs. All I know is that I, the guest, am caught between a rock and a hard place when it comes to eating at WDW. I don't think the restaurant choices are 'all that and a bag of chips' anymore. There is a huge sameness to them...nothing special about each one. And the menus are ridiculously similar. So now.....I tend to eat more counter service, with one or two 'nicer' table service meals. So, obviously the dining plan isn't going to work for me.
And I am one of those people who has no issue booking ADRs 6 months out. I know where I want to eat, and want to get the times that I want, so the 6 month window works very well for me.
And as noted by many here already....many, many guests tend to forget to add gratuities when figuring out their daily food costs. And that can add a huge chunk of change to your final accounting!!!!
