Yes, you can bring a cooler into Epcot and other Disney World parks in 2026, provided it adheres to strict size and safety regulations. The cooler—whether hard-sided or a soft-sided bag—must be no larger than 24 inches long x 15 inches wide x 18 inches high (61 cm x 38 cm x 46 cm). A crucial rule updated in recent years is that loose or dry ice is prohibited; you must use reusable ice packs or seal your ice in Ziploc bags to prevent leakage during security screenings. Additionally, glass containers and alcoholic beverages are strictly forbidden. Most guests find that a small, soft-sided insulated backpack is the most practical choice for navigating the park while keeping water and snacks cold. Be aware that all coolers are subject to manual inspection or X-ray at the "AdventHealth" security checkpoints. If you bring a cooler that exceeds the size limit, you will be required to rent a locker outside the park or return the item to your vehicle, as Disney does not allow "oversized" storage inside the gates.
