Yes, soft-sided coolers are fully allowed in all Walt Disney World theme parks, provided they adhere to specific size and ice regulations. In 2026, your cooler (or any bag) cannot be larger than 24" long x 15" wide x 18" high. Crucially, you cannot use loose ice or dry ice; all cooling must be done with reusable ice packs. This rule was implemented to speed up security screenings, as loose ice makes it difficult for guards to see the bottom of the bag. Soft coolers are a favorite "pro-tip" for families because they can be easily squished into the storage basket of a stroller or a standard rental locker. While you can bring your own food and non-alcoholic drinks, remember that you are not allowed to bring glass containers (except for small baby food jars) or any form of alcohol. A soft cooler filled with frozen water bottles is the best way to stay hydrated and save money in the intense Florida heat.
