Hi Rebecca,
We can't personally guarantee the safety of any food at Walt Disney World, (I'm not a doctor or nutritionist) but I can give you the DoleWhip ingredients and some other information.
Doles Whips are made of: Water, Sugar, Dextrose, Pineapple Juice Concentrate, Coconut Oil,
Stabilizers (Cellulose, Xanthan Gum, Locust Bean, Karaya Gum, Pectin),
Silicon Dioxide (Anticaking), Corn Syrup Solids, Citric Acid, Sodium
Caseinate (A Milk Derivative), Artificial Flavor, Potassium & Sodium
Phosphate, Mono & Diglycerides, Artificial Color (Yellow 5 &
6), Soy Lecithin.
As you can see, coconut oil is an ingredient, so that may pose an issue for you.
If you need more consultation about your issues, please feel
free to contact the Special Diets department at Walt Disney World. They can be reached at special.diets@disneyworld.com. They have been a great help to many guests and can give you all the information you need to make informed decisions about safe dining at Walt Disney World.
Good luck with your planning. Please let us know if you have additional questions.
