Did you also call? I needed Sept 26th-Oct 4th. Sept 26th is not one of the dates included in the posted dates. However, I called and the CM was able to get it for me, just not in a standard room. I had to go with a king room for just that one night. The AP code beat my
free dining, so I switched and now I don't have to buy another one of those one day park tickets I don't need. With the money I saved, I was able to purchase the basic
DDP just for the 26th, then upgrade to the DxDDP for the next seven nights, and Disney still owed my credit card 47.00.

I feel like I'm getting the DxDDP for free now.
