Where is your data to back up that people with allergies have a hard time being taken seriously at Disney in particular? Disney is horrible at many things, but they actually take allergies in every single case I've seen, very seriously.
I have family and friends with real allergies too and it's always taken seriously.
I've seen WDW staff bungle food allergies multiple times, including my most recent visit. I will share not to debate what happened, but to inform everyone that WDW is not perfect.
When we made ADR, we reported allergy. Person w allergy requested, and ordered off the allergen menu.
What I think happened is waitperson was new, they put in most of the food order, but forgot to add that person's order.
All the other food arrived, but was delivered by kitchen staff. They dropped off food and quickly left. They did not stop to ask if the food looked correct.
Finally, we get attention of our waitperson, to ask about missing food. They don't explain, but run away from table with a panicked expression saying they will, 'check.' The rest of the food is cold and congealing, so we start to eat. Good thing. We entirely finish food, and allergen food is still missing.
Finally, a plate of food is served to the person with the allergy, but it doesn't look like allergen-friendly food. Again, it is delivered by kitchen staff who drop off the plate and run away. No opportunity to ask anything. There is no allergen tag. LUCKILY the person with the food allergy didn't eat any of it!
Turns out, the waitperson totally messed up order. When asked, they act annoyed, and ask of person who has now been waiting over an hour for some food, "Do you STILL want your lunch?" And only a
very cursory mumbled apology. THEIR mistake could have been FATAL!
So now we have been seated for a long time. We decide to ask if we can talk to a manager. Allergen food finally arrives just ahead of manager.
Mind, I'm normally tolerant of waitstaff, but the rest of our service was also horrible. All of our water/soft drinks are long gone/no refills, table is littered with appetizer plates that were not cleared, etc.
After that, waitperson suddenly becomes very apologetic.
Their mistake could have been fatal. Luckily, the manager appeared to take the situation seriously.
Sadly, this is not the first time WDW has bungled an allergen order in the past 2-3 years.
