How?
If that's what you think, you're missing the point many of us are saying... your son shouldn't have to pay ANY medical bills... co pay or otherwise. Disney should handle all of that.
I still don't understand why your son's family left a day early. That extra day (Thursday to Friday) could have given you more time together as a family.
I am in total agreement. OP- I feel badly that your grands had that terrifying experience. My DGD had multiple allergies at one stage in her life and food was always a challenge anywhere but Disney.
With that said, I cannot agree that Disney owes the family a redo, if that is what you want. You have never been specific in regards to the compensation you believe Disney owes you, so many of us are just trying to understand what you are asking for. Typically, if an incident arises that Disney wants to compensate for, they will offer time in a resort that is comparable to what you had booked when the incident occurred. WE had an unfortunate incident that I felt I needed to discuss with management and was offered two nights on a trip. Clearly, our issue did not involve a trip to the ER, however it was distressing to us and like you, left us feeling buyers remorse, if you will. Anyway, my DH reaction to that offer, which I never had asked for...I was already home and therefore expected nothing...was "Are they planning to fly us there?" No. Of course not. The offer was genuine, but using it was based on planning another trip, which I eventually did.
IMO- the decision to take the kids home does not merit that day returned to your family. Your son made a choice that I know we never would have made, and any loss or costs associated with that decision should fall on him. That time lost was a conscientious decision to cut a trip short, so why does Disney need to reimburse your family? I would think that a few days in a comparable lodging, along with Dr bills and copays reimbursed would be a fair answer to this, however if Disney chose to gift your family with more that would be nice. Not owed though.
In regards to a Chef's responsibility for any mistakes in foods handling for allergies, I believe that Disney has verbiage that covers them in the sad event that happens. I also feel very strongly that there is a reason that many restaurants do not try to accommodate may allergies and that involves the responsibility in the event a mistake occurs. For years the only destination we could travel to for any length of time was Disney because of the treatment provided to those with food borne allergies. I would hate to see the options reduced if Disney feels their liability is far too high and simply chooses to stop serving those with allergies.
. Friday you wrote that you were at YC for one more day. Later in the thread you said you spent two nights at PO, then moved to Melia to stay with your son's family for their trip, then moved to the YC for one night. I
