Can I bring my own food into theme parks and Disney Resort hotels?
Guests are allowed to bring food items—such as snacks or foods that do not require heating—into Disney theme parks. Inform a Security Cast Member of any food items when you enter the park.
If you are concerned that we may not offer foods that you are able to eat, learn how to make Special Dietary Requests.
