Shelf-stable snacks like chips, pretzels, protein bars or any other items packaged in sealed wrappers are permitted on every major cruise line. Just stick with store-bought goodies including candy, savory snacks, cookies or granola bars instead of whipping up a batch of homemade muffins or sandwiches to bring with you.

Yes, you are generally allowed to bring snacks on a cruise, but they must be pre-packaged and factory-sealed. Most major lines, including Royal Caribbean, Carnival, and Norwegian, have "sensible" snack policies that allow you to bring small quantities of dry snacks like crackers, granola bars, chips, or nuts. These items must remain in their original packaging to ensure they are shelf-stable and to prevent the introduction of pests or cross-contamination. You are strictly prohibited from bringing "open" or homemade food items, such as fresh fruit, meat, sandwiches, or leftovers, due to strict agricultural and health regulations. In 2026, many lines have also reinforced their policies regarding beverages: you are typically limited to 12 standard-sized cans or bottles of non-alcoholic drinks (like soda or water) per stateroom. While the ships are famously loaded with complimentary food, many travelers bring snacks to save money on shore excursions or to accommodate specific dietary needs that might be harder to find at the onboard 24-hour cafes.
