I haven't used the DP with
DVC yet as it wasn't available during my last trip, so instead we got the DDE. However, we do enjoy the DP and the ease of not having to worry about how much you are spending on food.
I think it is very reasonable unless you are staying for an extended amount of time. I'm going to have to run some figures for our next 2 trips to see if we'd be better off continuing to use the DDE or get the DP. Once I do those comparisons, I'll post my findings... (I have to factor in alcoholic beverages, and the fact that we typcially split a meal for lunch and don't get that many snacks, etc)...
Oh, one thing I was wondering about the DVC DP.... I know it applies to everyone on the ressie for the length of the stay, but what if you just don't list the kids on the ressie? I mean if it were 2 adults and 2 kids and you knew that one of your kids wouldn't eat enough to justify the DP for them, you could simply put the 2 adults and the 1 child on the ressie and you would only have to get the DP for those 3... I mean to stay at DVC we don't have our park tickets linked to our room keys so not everyone has to be on there...
