As I've posted before, this is somewhat more complicated with
DVC and the DDP. DVC says it must be added prior and you can't change it at check in. That could certainly present the catch 22, especially in this situation. And it is my opinion that the party size and last minute or part of the trip guests are far more common for DVC that otherwise. I believe this is an area that DVC and/or Disney will have to address at some point and come up with some guidelines that take this exact issue into account. That is if the program lasts beyond 2007 which I think may be a question mark at this time at least with how it's currently drawn up. I could easily see a change where all you have is snack credits and dining credits. Where you used 1 credit for a CS, 2 for some TS, 3 for other's and maybe 4 for Signature. With that type approach, even V & A becomes potentially workable under the plan. And I believe there are ways to manipulate this issue legally under the system. In this case you'd simply make 2 separate reservations and get the DDP for the applicable portion only. You might be beyond the intent but you'd certainly be within the rules.
