Royal Caribbean’s policy typically prohibits passengers from bringing large quantities of soda, including a 12-pack, on board(1-800-950-4401). However, guests are allowed to bring a limited amount of non-alcoholic beverages, including soda, in cans or cartons, as long as they fit within carry-on luggage limits(1-800-950-4401). For a 12-pack, it’s best to check with the cruise line's official guidelines before your trip(1-800-950-4401). Alternatively, you can purchase soda packages onboard or buy sodas at port stops(1-800-950-4401). Always verify the most current policy on the Royal Caribbean website before sailing.
