That could be true, although there's no way to know for sure.
Personally, I'll keep blaming the dining plan. And yes, I know it's been a wild success from a financial point of view -- especially the "free" dining that isn't really free -- but I'm in the crowd that thinks it's been the biggest contributor to the overall decline in Disney dining, from the availability of reservations to the quality and variety of food.
I've never been one to use the
DDP (free or otherwise), and also took a long break from the parks so I missed a lot of the early days of the DDP.
That being said... I'd have to agree, if nothing more, for these two reasons.
1. The DDP, for better or worse, Has helped drive some people to try TS restaurants that maybe wouldn't have tried them otherwise. As a result, you run into less availability because of more people eating TS that may not have thought about doing a TS before.
2. As part of the above, You end up having people who are expecting Burgers, Hotdogs, Pizza, chicken fingers, and other usual fast food/counter Service type meals going to TS restaurants. The result is that they are less likely to enjoy some of the more exotic or unique offerings that Disney TS used to be known for. This then leads to Disney removing some of the more exotic or unique items from the menu because there are selling very few of them compared to the more "bland" and mainstream items.
So I can totally see the Paid DDP contributing to the decline on both fronts. More people in the seats, resulting in less availability.... and People eating more "mainstream" food while in those seats, resulting in more "mainstreamed" specialty dishes (example: Mexico becoming more Americanized Mexican vs Mexican Mexican food) and less unique items on the menu.
The question about the "Free DDP" promo's leading to "cheaper" food options is another debate entirely.
And since I've decided to post in one of these threads, Let me add another voice to the "It's a good idea" camp. I enjoy doing walk ups, or being able to decide much closer to the trip what I'm in the mood for. besides not being a 180day uber planner (My last trip I decided on and planned in less than 3 months), I'm also a much more laid back kind of person. I see this policy change as a way for disney to help discourage the multiple ressies for a single meal way of making ADR's that some people recommend planning. At the very least, it helps add another reason for people to make sure they cancel their ADR as they get closer to their dates than just keep them. (You know... something beyond the kindness in their heart and thinking of others, but something that gives them a personal reason to do it.).
Disney being Disney, I don't expect then to be nazi's about making sure you cancel before 24hrs or else. They understand things happen, and aren't going to be viscous in their application of the penalties. Delayed flights....Illness.... transportation issues, There are legit reasons a person may not be able to make their ADR, and based off the information we've gotten from CM's here and what we know about Disney's Guest Relations, It's obvious that the goal here isn't to nickle and dime guests to make an extra few bucks from last minute cancels or no shows. They are simply trying to do what they can to prevent the abuse of the ADR system which has resulted in major availability issues due to phantom reservations that someone had no intention of using but never canceled.
