I too DMRick would be interested in the name/source you have.
Just a few of my thoughts:
I have heard many times over the years that DL and WDW visitors are two different creatures.
I have heard that DL NEEDS AP-ers to keep them going. Local traffic helps them.
I have heard the opposite for WDW. They are sustained more by non-locals.
(All heresay)
A CA friend once mentioned to me how surprised he was of the non-locals at WDW.
A DL AP was pretty cheap. I do know DL locals the price increase chased away, or at least took them down to seasonal passes or occasional visitor.
As a WDW local, I may not spend money on hotels. But we eat at WDW year round. More often than not we use DDE. But we still eat there on a regular basis. And I certainly buy souveies, as most of us do I think. We are all Disney nuts/addicts after all.
And on-site rooms are being booked up, often to capacity. It is not uncommon for me to talk to locals who tried to find a last minute on-site room and are told NO availability or VERY limited. (Like one type of room at one resort.)
Bookings are up from everything I have seen and heard.
I think part of the issues Disney creates are due to the right hand not knowing what the left hand is doing. (Or the right hand not even knowing the left hand is even effected or there!

)
IMO only there are communication, system capatability, and understaffing issues to name a few.
And if a policy is not to allow something, then the system should not allow configuration or selection where it does. And I think that has been part of the problem and where some of the inconsistencies come in.
We all read here some guests were buying kid's APs to get room discounts. And Disney seemed to turn their head.
Then they came out with the AP holder had to pay by credit card. (And what child has a credit card?) Now it seems their intention was only adult AP to go against the room for a discount. But all they had to do was make that clear in the beginning.
I have seen official wording specifying an adult AP is required. Now if it will be enforced, that will be another thing.
We all know Disney's policies and procedures are as firm as jello. Hence some of the issues they create on their own. (Again just MHO.)
All that being said, we all know too that having AP's and not being a local makes guests want to return to WDW more often "to get their money's worth" from their APs.
