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. A guest's age is established upon the first date of sailing.

Royal Caribbean maintains a structured "Age Policy" that defines adulthood differently based on the ship's departure port and the specific activity. For sailings originating in North America or the Caribbean, the minimum age to sail unaccompanied is 21, and the minimum drinking age is also 21. However, for cruises departing from South America, Europe, Asia, Australia, and New Zealand, the minimum age to sail unaccompanied and the minimum drinking age drop to 18. In the onboard casinos, the age of entry is generally 18 (except for Alaska sailings, which require 21). Beyond these legalities, Royal Caribbean has expanded its "adults-only" spaces in 2026 to cater to travelers seeking a child-free environment. This includes the classic Solarium (for guests 16+) and the newer Hideaway Beach at Perfect Day at CocoCay, which is the cruise line's first dedicated adults-only oasis on their private island. While Royal Caribbean remains a premier family brand, these policies ensure that adult travelers can find sanctuary in refined, age-restricted zones away from the high-energy family areas.
