This family has a definite problem with Disney, and everybody either jumps down her throat, or says, "move along now little doggie."
Now, if this were a complaint about ants in the rooms, or some CRO not doing some code right, the story would be different.
I have read the posts here, and the previous thread. And, although most of you don't want to hear this, I think this lady is deserving of some compensation. It is fairly clear that the entire family got sick, at the same time, after eating the same food. It is also clear that, even if it was not HDD food, it was disney food as they only ate disney food for several days before.
I don't care if nobody else complained. SO WHAT! That has absolutely no bearing whatsoever on this family's claim for reimbursement. What other people do or do not do has no effect on their claim. What does have an effect on their claim is what they do, and what happens to them.
So Disney says no one else complained. That does not mean that no one else got sick. It simply means that no one else complained. Although they can put that up as a defense, I can guarantee that it is as easy to shoot holes through as a piece of tissue paper.
All4lol, file a claim in small claims court. Determine your damages, losts $$ for tickets, days in hotel, dr. expenses, etc. and, as they say on TV, take 'em to Court. I'll place my bets with you, and not disney in this fight.
