I don't know, maybe for them to do something to rectify their mistake?
Just because they're Disney doesn't mean we should turn a blind eye to massive mistakes in customer service - heck it actually means they really need to step up to the plate... seeing as how it's their legendary (quickly by all reports going down the sink hole) customer service that justifies the outrageous prices.
At the least I would like to see some form of equal accountability - I mean they charge us when we mess up and have to cancel at the last moment, seems to me the least they can do is hold themselves to the same high standards.
They mess up - it's too late for her to resolve it to her satisfaction, they find a way to make it up... why is that so hard to accept?
