Why do people buy the DDP and then not know ahead of time what is and what is not included or how it works? How people plan a disney vacation without truly planning it is beyond me.

sigh.....
I haven't ever done the DDP but we are doing it this time. I have had my lists of what snacks are included at each place printed for weeks. I have a list of all restaurants including CS and snack places that are on the DDP. I have maps with all the places on them. I have my list of top CS places for food that I want. I know that anything above 3.00 is most likely a deal on the DDP for a snack- and to try and only use credits for things closer to 4.00.
This isn't about "disney novices". I'm a novice- I haven't been since I was 21 and this is the first "adult" trip at disney for me. I'm not going into it blind. I'm planning it, figuring out the best times for things, how the FP's work...
Not everyone is a disboarder. To me disboards has been the thing that has allowed me to become informed about WDW/DL and become the obsessive planner I am. Frankly, if Disney were to really give the full story on the DDP by saying something like: "Make your reservations 180 days if you want to eat at our most popular places, expect long waits, go on allearsnet and find out what's included and expect at times to be confused or around others who are confused" would anybody buy that? They sell it as a meal plan, advise you to make ADR's, give you some general information and then their duty is done. If you are a disboarder, know a Disney addict who can help you, use a TA or stumble on this website or another such as allears, you are in luck. Otherwise you are going in thinking you have done all you can, pre purcahsed yoru tickets, meals, and room and probably think you are very prepared. People can only make use of the information they know how to get.
Not everyone has the time or inclination to research their vacations and many of them still have a wonderful time! Last minute ADR's do exist, you don't need to call 180 days out to get the vast majority of ADR's and since the Disney Dining number is given to you when you book a pkg., most probably know to call at some point. In the end, for the most, part everyone I see appears to be having a marvelous time and who knows how much planning they put into that. I don't find the waits at the cs places much worse than they used to be, and frankly I have no problem if my wait is maybe 5-10 minutes longer. The DDP is a fact of life, I have used it, not used it, gone before and after its inception and my overall feeling is that WDW is still a great place to vacation and eat.
I think the DDP is one factor in the way things are around WDW now. But to me the bigger picture is the rise in park attendance in general. I find very much the same atmospher at the
Disneyland restaurants, you can't be as last minute anymore and DL doesn't have a DDP. They have a meal plan that practially nobody purchases. And DL is way more crowded too. Disney and the travel industry in general are hopping right now. The DDP is just one of the things Disney has come up with to market their product.
I like the DDP, but my kids are only 10 and 12 and paying that much for that much food is not great for us. I do think some of the menu's have changed a bit, WCC comes to mind but the buffets haven't changed in my experience. I do feel sorry for the locals who can't get the last minute ADR's they used to, but again, the parks are more crowded with DDP'ers and non DDP guests. So who knows? I think in the end, if you find the DDP really cramps your WDW vacation style, you should just find somewhere else to spend your money or do what one of the posters on this thread is doing: go to WDW but eat many meals offsite.
