Coolers, whether soft-sided or hard, are permitted but must be no larger than 24 long x 15 wide x 18 high, and loose or dry ice is not permitted inside the coolers.

Soft-sided coolers are permitted at Disneyland Resort as long as they adhere to specific size and safety regulations. The cooler, along with any other bag or backpack, must not exceed 24 inches long by 15 inches wide by 18 inches high. A crucial rule to remember is that loose ice and dry ice are strictly prohibited; you must use reusable ice packs or sealable bags filled with ice to keep your items cold. Large, hard-sided coolers are not allowed inside the theme parks, though they can be stored in the extra-large lockers located outside the main entrance. Security will inspect all coolers at the checkpoint, so ensure no glass containers or alcohol are packed inside.
