Yes, you are welcome to bring soda on a Disney Cruise, but it must follow strict guidelines: it must be factory-sealed (bottles or cans) and it must be in your carry-on luggage. You are prohibited from packing soda in your checked bags; if security finds beverage containers in checked luggage, they may remove them or the bags may be delayed. While you can bring your own, it is important to remember that soda is already included in your cruise fare on Disney Cruise Line. You can find free soda stations on the pool deck and enjoy complimentary soda at lunch and dinner in the main dining rooms. You only pay for soda if you order it through room service, at a bar, or at the theater concession stand. Because your stateroom may not be ready until the afternoon of embarkation, the "pro-tip" for 2026 is to bring only a small amount of your favorite niche brand, as you will have to carry that bag with you around the ship until your room opens.
