Yes, you can bring containers into Disney theme parks in 2026, but they must comply with strict size and safety regulations. Backpacks, coolers, and bags must not exceed 24 inches long x 15 inches wide x 18 inches high (61 cm x 38 cm x 46 cm). A critical rule for 2026 is that glass containers are strictly prohibited, with the only exception being small baby food jars. Additionally, loose or dry ice is not permitted in any containers; if you need to keep food or drinks cold, you must use reusable ice packs. Food and non-alcoholic beverages are allowed for self-consumption as long as they do not require heating or refrigeration. All containers are subject to search at the security checkpoints, and any item deemed potentially harmful or disruptive (such as folding chairs or certain types of wagons) may be barred from entry to ensure the safety and flow of guests.
