For those who, for some reason, don't want to believe people get food poisoning at Disney, it's common. When my daughter got it at Flame Tree, she was so sick we had to take her to an emergency center. They told us it was very common to have Disney quests come in with fp. They had already had several that week. If someone has actual fp, they will know it. They will have fairly intense stomach pain along with the typical virus symptoms.
We were able to pinpoint Flame Tree, as we were both watching our calories, so we shared all our meals except for Flame Tree as she got meat and I wasn't eating meat. And, to top it off, I told her it didn't smell right, but she and her father said that it always smelled like that, and she ate it anyway. We had been there for seven days and had eaten every meal in the parks and our resort.
Some of the time, people simply catch a 24 hour virus while there and think it's fp, but there are a lot who actually get fp from the food. My daughter was sick for several days. They were able to stop the vomiting and stomach pain, but the weakness latest many days. Luckily, she got sick two days before we were to come home.
We had already had a great trip.
