How old does a baby need to be to cruise with Royal Caribbean?
Most sailings require infants to be at least 6 months old on the first day of the cruise. Longer stretches at sea raise the bar. Transatlantic, transpacific, Hawaii, select South American itineraries, and any cruise with three or more consecutive sea days need the baby to be at least 12 months old on day one. Underage infants are denied boarding, and that denial does not come with a refund, so confirm the rule for your specific sailing before you pack the diaper bag.
