Cruises are a fantastic way to travel, but if you’re planning a trip with younger guests, you might be wondering: how old do you have to be to go on a cruise? The answer varies depending on the cruise line, destination, and type of sailing. This guide breaks down age requirements, policies for infants, children, and adults, and important rules for alcohol consumption, gambling, and more.
Minimum Age Requirement for Cruises
Most cruise lines enforce a minimum age requirement to ensure the safety and enjoyment of all guests. While policies vary, the general rule is that passengers must be at least 6 months old for standard sailings. For transatlantic, Hawaii, South America, and other longer sailings originating in remote locations, infants must be at least 12 months old on the date of departure.
Infant Policy and Young Infants
The infant policy is strictly enforced across all major cruise lines, including Royal Caribbean, Disney Cruise, and Carnival. If a young infant does not meet the minimum age, boarding may be denied without other compensation. Parents should carefully review the infant policy when booking their cruise.
Minimum Age to Sail Without a Parent or Guardian
If a child is traveling without a parent or guardian, they typically must be at least 18 years of age. For some sailings originating in the United States, such as Royal Caribbean itineraries, at least one guest in each cabin must be 21 years of age or older. This applies even if connecting staterooms are booked.
This rule ensures that a responsible adult is present in each cabin to oversee any younger passengers. In addition to meeting the age requirements, some cruise lines may require minors traveling without a parent to carry a signed and notarized consent form from a legal guardian. This documentation helps avoid any issues when boarding or at port stops, especially on international sailings where local laws may require proof of parental consent for underage travelers.
Special Considerations for Underage Married Couples
Some cruise lines allow underage married couples (where both guests are younger than 21) to sail without an older adult, provided they show proof of marriage. This policy varies by ship and itinerary, so check with guest services before booking.
In these cases, underage married couples must present official marriage certificates at boarding to satisfy the cruise line’s age requirements. However, even with this exception, the couple may still be subject to certain restrictions, such as limited access to alcoholic beverages or adult-themed events. This flexibility is more common on cruises departing from South America or Europe but much less likely on family-oriented lines such as Disney Cruise.
Age Restrictions for Same Cabin Guests
Most cruise lines require that at least one person in each cabin be over 21 years of age. This is particularly common for Royal Caribbean, where the Royal Caribbean reserves the right to enforce this policy across all sailings.
This requirement applies even if younger guests are legally considered adults at age 18. The rule promotes responsible behavior and prevents underage drinking or irresponsible behavior in the cabin. Some cruise lines make exceptions for families booking multiple connecting staterooms as long as the parent or guardian occupies one of the cabins. For groups of young adults traveling together, this rule can significantly influence how cabins are assigned and how passengers are grouped.
Minimum Drinking Age Requirements
The minimum drinking age on most sailings is 21. However, for cruises departing from certain regions, such as South America or Europe, the alcohol policy may lower the age to 18.
Alcohol Consumption and Alcoholic Beverages
Even if local laws at private destinations permit alcohol consumption at a younger age, cruise lines typically follow the alcohol policy set for the ship, not the port. Royal Caribbean reserves the right to refuse alcoholic beverages to guests showing signs of irresponsible behavior.
Gambling Policy for Guests
In casino areas, the minimum age to gamble is typically 18 years of age. However, on Alaska sailings or Hawaii cruises, local laws require all passengers to be 21 years of age to enter the casino. This gambling policy for guests is strictly enforced.
Fitness and Spa Facilities Age Restrictions
Children under 16 years of age are usually not allowed to use the fitness facilities or enter spa facilities without being accompanied by a parent or guardian. Some adult-themed events, night clubs, and shore excursions may also have higher age requirements—usually 18 years of age or older.
Disney Cruise Line Minimum Age Policies
The minimum age requirements on Disney Cruise Line align closely with industry standards. Infants must be at least 6 months old for most sailings. Certain shore excursions may also have age restrictions to ensure safety. Additionally, adult-only areas, such as the spa facilities and adult nightclubs, are limited to guests who are 18 years of age or older.
What Happens if You Don’t Meet Age Requirements?
If a guest’s age doesn’t meet the minimum age requirement for a particular cruise, denied boarding may occur at the guest’s own expense. This applies even if the person is traveling with an accompanying guest who meets the age threshold. Always double-check age restrictions before finalizing your booking.
Parent or Guardian Responsibilities
Parent or guardian responsibilities extend beyond booking. During the cruise, parents are responsible for ensuring their children follow all age requirements for fitness facilities, spa facilities, adult-themed events, and alcohol consumption.
Age Requirements by Popular Cruise Lines

Sailing with Minor Children
If minor children are traveling without both parents, some cruise lines may require notarized legal guardian consent forms. This is especially common on international sailings originating from South America and Hawaii. These rules help comply with local laws and prevent issues at port.
