Royal Caribbean International has a strict safety policy regarding pregnancy in 2026: they cannot accept guests who will be more than 23 weeks pregnant at any time during the cruise or "CruiseTour." This rule is strictly enforced because cruise ships do not have a dedicated Obstetrician/Gynecologist on board, and specialized neonatal equipment is not available for premature births at sea. If you are pregnant, you are required to fill out a Public Health Questionnaire at the pier attesting that you are under the 23-week limit. If you have already booked a cruise and find you will exceed this limit, you should contact the cruise line immediately to discuss cancellation or rebooking options, as they will deny boarding without a refund if the policy is violated. It is also highly recommended to carry a letter from your doctor stating your "due date" and that you are "fit to travel," especially if you are close to the cutoff, as port officials have the final authority to determine if a guest is safe to board.
