I think tup1830 summarized the concerns quite succinctly, so thank you for posting. I feel for Tink's mom as well, and I understand the frustrations she, and her family, felt.
Disney sells itself as a premier destination with world class service, amenities, and opportunities for fun. They tout their customers service and "magic" very highly in all of their marketing. As such, the standard is set by Disney Parks and Resorts, not by the guest, in my opinion. When this falls short, and even falls to the level of a local park, movie theater, or
WalMart, then Disney has failed to live up to their own, highly touted, expectations.
It has been discussed on here in many threads how Disney service, food, and value for the price is not close to what it was last century. Throughout the new millennium, these aspects of a Disney trip has dropped off significantly, and continues to do so. This isn't a new topic for us, as we've talked about it. We, the hard core Disney fans, have figured out the work around for many issues, learned to take poor service in stride since we remember how it was and plan to return regardless, and know how to bend the system to meet our needs. We are a vast minority, in both Disney park guests and
DVC owners. Thus it is easy for us to use our experience to brush off poor service, bland food, and ride breakage.
However, what if the OP's family didn't have the money yet saved for many years to afford that one magical trip to Disney World? Many park guests are in this category. They arrive expecting great service only to get attitude by the management and poor information from cast members. A travesty, really. It makes our job of communicating the magic that much more difficult. Luckily for the family, the OP has done her homework and knew many things the general public did not know. Yet, she still put her faith in the cast members when the information they vehemently provided went against conventional wisdom (from the DIS) and got burned the same CMs and their managers.
The only change to the thread I'd hope from the OP was to list the grievances out, so we can see them, since we've heard pieces as the conversation went along. We can't help (or sympathize) if we don't know the details. Otherwise, I think she was wronged in more instances then she should have been, which not only destroyed her family's experience with Disney, but more importantly causes her to question her own loyalty to the Disney product.
This is where Disney will be in trouble, if they don't make the corrections. Word of mouth from their champions is vastly important to a guest deciding to take their vacation in Orlando or Anaheim, more so than the marketing. If a champion is disillusioned, they can wreak havoc on guest attendance numbers simply by talking friends, family, and coworkers out of visiting.
