Wow - This thread has gotten interesting!
My 2 cents - I agree with the OP for being upset. However, I think (zippering up my flame retardent suit) that this thread brings out the real issue - Disney's failure to recognize and admit their mistakes and make up for it.
95% of the time, I deal with delightful CM's who make my vacation all the more magical. However, I havde dealt on occassion with rude, unknowledgeable CM's, who make things difficult. At times, it's been so bad that I've approached someone at management, and the response always seems to be the same: I get quoted back some "policy" of theirs that gives Disney immunity from responsibility. Just suck it up, apologize, and make up for it. What's so hard about that?
That being said, sure, there are times when bad things happen that management is great about it and more than willing to right a wrong, but far too often, to myself, and to others, Disney turns a deaf ear to taking resposibility for a mistake in which they made. It seems that's what happened with the OP in her case.
