As long as bags are less than 24? long x 15? wide x 18? high, they are allowed, including backpacks and fanny packs. Backpacks are great because of their multiple storage departments, and you can always store them in a locker if you need a break during the day.

Disney parks maintain a relatively flexible bag policy, but there are strict size and safety restrictions you must follow in 2026. Guests are allowed to bring backpacks, purses, and cooler bags as long as they do not exceed 24 inches long x 15 inches wide x 18 inches high (61 cm x 38 cm x 46 cm). All bags are subject to a security screening, which often involves advanced "contactless" scanners that allow you to walk through without removing your belongings, though manual inspections still occur. Prohibited items that cannot be in your bag include glass containers (except for small baby food jars), alcohol, and "stroller wagons." If you are bringing a cooler bag, it is a peer-to-peer "pro-tip" to remember that loose ice and dry ice are strictly forbidden; you must use re-freezable ice packs instead. While you can bring your own food and non-alcoholic drinks, the bag must be small enough to be stowed during rides or held in your lap. Most rides provide small pouches or floor space for bags, making it easy to carry essentials like sunscreen, portable chargers, and snacks.
