No Guest younger than the age twenty-one (21) will be assigned to a stateroom unless accompanied in the same stateroom by an adult twenty-one (21) years old or older.

Royal Caribbean has several specific age-related policies that vary by region and activity. For most sailings departing from North America, the minimum age to sail is 6 months, though this increases to 12 months for trans-oceanic voyages and certain remote itineraries. To book a stateroom, at least one guest in the cabin must be 21 years of age or older, except for married couples or those sailing from European or Australian ports where the limit is often 18. Regarding alcohol, the drinking age on ships departing from North America is 21, while on cruises departing from Europe, Asia, Australia, and South America, the age is 18. For the "Adventure Ocean" youth programs, children must be at least 3 years old and fully potty-trained to participate in the main groups, though the "Royal Babies & Tots" nursery is available for younger infants at an hourly fee. In 2026, these rules are strictly enforced via the SeaPass card, which tracks the birth date of every passenger to ensure compliance with international maritime and safety regulations.
