Both of my kids are allergic to peanuts, tree nuts and soybeans! To say it is stressful when eating out is an understatement! That's why we LOVE visiting Disney World. They are so accomodating and wonderful. The last I heard, and we do check at every food stand or restaurant we go, they use Canola oil. They said this is due to the kids being allergic to soy and nuts. I would still check, but anytime you order food at any place in Disney you can ask for the ingredients for that particular food and they will locate it for you. Did this several times at counter services. Just ask and I'm sure they will bend over backwards to get you your answer, but keep your fingers crossed that the information I was told is true throughout the park and Canola oil is the oil they use. Good luck.
