Unfortunately us AP holders do not get a discount on the DDP, In fact we have to give up our AP discounts on the room and must buy at least a one day MYW ticket in order to get the DDP (which we must pay full price for). We can get the Disney Dining Experience card for $65.00 which gives us 20% off most TS meals and even some CS meals (at resorts that do not have a TS and at AK--however, with the new Yak Yeti restaurant coming in I don't know if we'll continue to get the DDE discount there

).
The way I have it figured: if I stayed at a value resort (POP) I'd lose about $162.00 by giving up the AP discount (if AP discounts for Dec are what they are for Sept), plus have to pay $71.36 for a one day MYW ticket (which I don't need---after my Sept trip I will have three one day MYW tickets from trips where I've had to purchase them to get the DDP). Then I'd have to pay $311.92 for the DDP ($38.99x8 nights) and I'd still have to pay OOP for two character breakfasts, because I wouldn't have enough credits to cover all my TS meals=$19.98x2=$39.96 (with the DDE discount plus tax and tip). That means that I'd have to pay $585.24 compared to the about $482.00 I'd be paying for the same food if I just used my DDE card and used the AP discount for the room. I've used the DDP Sept '05, May '06, Sept '06, May '07, and will be using it again Sept-Oct '07 (thanks to the Bounce Back program). It's alot of food and I've found in the past that I frequently skipped desserts (especially CS desserts) as the week wore on and I've always had snacks left over. I also have a tendency to drink more sodas than I normally would, because they are included on the DDP. However, I love the convenience of the DDP and knowing that just about everything is paid for, before I arrive. Of course if no AP discounts are offered for the rooms during that time I'll definitely go with the DDP and just add the required one day MYW ticket to my current stash. Oh! decisions, decisions!!
