On cruises of 6 days or longer, no more than two bags, per person. Each checked bag and carry-on bag should not weigh more than 50 pounds and, when lying flat, bags must not exceed 16 inches high, by 24 inches wide (the length of the bag is not a factor). For security screening purposes, all luggage should be unlocked.

For a standard 7-night cruise in 2026, the recommended amount of luggage is one large checked suitcase (up to 50 lbs / 23 kg) and one small carry-on bag per person. While most cruise lines like Royal Caribbean and Carnival officially have an "unlimited" baggage policy, the physical size of the stateroom is the ultimate constraint; standard cabins have very limited floor space, and storing more than two large suitcases under the bed can be difficult. Your carry-on bag is essential for "boarding day" because it can take several hours for your checked luggage to be delivered to your room; you should pack your medications, a change of clothes, swimwear, and important documents in this bag. For "fly-cruises," you are further restricted by airline weight limits. Experienced cruisers suggest a "mix-and-match" wardrobe to save space, but given the variety of "Formal Nights," shore excursions, and pool days, one full-size suitcase is usually the minimum needed to be properly prepared for all ship activities.
