You can bring a small cooler into Disney theme parks, but it must adhere to strict size and safety regulations. In 2026, coolers must be no larger than 24" long x 15" wide x 18" high (61 cm x 38 cm x 46 cm). Additionally, loose or dry ice is strictly prohibited inside the parks; you must use reusable ice packs or frozen water bottles to keep your items cold. Coolers are generally permitted at outdoor locations but may be restricted in certain indoor theater venues. While you are welcome to bring your own food and non-alcoholic beverages, glass containers (except for small baby food jars) and alcoholic drinks are not allowed. Most guests find that a soft-sided "backpack cooler" is the most efficient way to carry refreshments while staying within the allowed dimensions.
