Actually the DDP itself is not responsible for anything.
There's someone, somewhere, who decided that filling resorts that would otherwise be half empty, getting $38.99 per day per guest months in advance and the guarantee that these guests would spend the majority (if not the totality) of their vacation money on Disney property, is not quite enough.
Wanna blame someone, blame that person.
I can only speak for our experiences but that's exactly what we got on our trips. We've traveled through most of Europe, a good part of the US, and many other countries. We have NEVER gotten that kind of service anywhere but at Disney. Geesh... my mom's 58. You think she asked to come back to WDW because she wants to ride Pooh again ?
