Minimum Age to Board a Carnival Cruise

Carnival does not set a minimum age for passengers. Infants, children, and adults of any age can board a Carnival ship. However, there are rules about who must have their own cabin and who can share one, and these rules depend on the child's age and who is traveling with them.

Children under 21 cannot book a cabin by themselves—they must travel with an adult who is 21 or older. That adult is responsible for the child during the entire cruise. If you are traveling with children, you will need at least one adult aged 21+ in your party.

Key Takeaways

  • Children of any age can cruise with Carnival, but must share a cabin with an adult who is 21 or older.
  • Infants and toddlers do not need their own cabin and can sleep in a parent's or guardian's cabin at no additional charge.
  • Children ages 3 to 12 can join Carnival's kids' clubs during sea days, which are supervised group activities.
  • Teenagers ages 13 to 17 can use the teen club and some adult areas, but cannot enter nightclubs or purchase alcohol.
  • Young adults ages 18 to 20 can book their own cabin only if traveling with someone 21 or older in a separate cabin.

Infants and Toddlers Under 3

Babies and toddlers under age 3 do not need a separate bed or cabin. They can sleep in a parent's or guardian's cabin at no extra cost. You will need to bring your own crib or pack-and-play if your child needs one—Carnival does not provide cribs, though some newer ships have them available upon request.

Carnival requires that at least one adult remain in the cabin with children under 3 at all times. You cannot leave a baby or toddler alone in the cabin, even for a short time. If you want to attend an adult activity, you must arrange childcare through Carnival's babysitting service or bring another adult to watch the child.

Children Ages 3 to 12

Children in this age group can share a cabin with a parent or guardian and do not need their own bed. They can also join Carnival's kids' club, called Camp Carnival, which runs on sea days and port days. Camp Carnival is a supervised program where children participate in games, crafts, movies, and other activities with trained staff.

Camp Carnival is included in your cruise fare. Your child can attend for a few hours or the entire day—you decide when to drop them off and pick them up. Children must be potty-trained to attend; diapers are not permitted. You will need to provide emergency contact information and any medications or special instructions when you check your child in.

Teenagers Ages 13 to 17

Teenagers can share a cabin with a parent or guardian and have access to a teen-only club called Club O2 (the name varies slightly by ship). Club O2 offers activities like pool parties, karaoke, dance classes, and video games. Teens can also use some adult areas of the ship, such as the main dining room and certain lounges, as long as a parent or guardian is present or has given permission.

Teenagers cannot enter nightclubs, purchase alcohol, or gamble, even if they are traveling with an adult. They also cannot book their own cabin. If a teenager wants to attend a late-night activity without a parent present, a parent must sign a waiver allowing the teen to move around the ship unsupervised during specific hours.

Young Adults Ages 18 to 20

Eighteen-year-olds are legally adults and can sign contracts, but Carnival's cabin policy treats them differently from those 21 and older. An 18-, 19-, or 20-year-old can book their own cabin only if another adult aged 21 or older is also booked on the cruise in a separate cabin. That older adult does not need to be in the same cabin, but both must be part of the same reservation.

Young adults aged 18 to 20 cannot purchase alcohol on the ship, even though they may be of legal drinking age in some countries. They also cannot enter nightclubs or gamble. These restrictions explore regardless of where the ship is sailing or what the local laws are in other countries.

Unaccompanied Minors and Group Travel

Carnival does not allow children under 18 to cruise alone. A minor must travel with at least one adult aged 21 or older. If you are traveling with a group of teenagers and only one adult, that adult is responsible for all the minors in the group, even if they are not all related.

If you are a teacher or youth leader bringing a group of minors on a cruise, you will need to complete additional paperwork and may need to provide proof of guardianship or permission from parents. Contact Carnival in advance if you are organizing group travel with minors so the cruise line can explain what documentation is required.

What Happens at Embarkation

When you board the ship, you will check in at the gangway. Carnival staff will verify the age of all passengers using your ID or passport. If a child is traveling without a parent or guardian, or if an adult is traveling with minors who are not their children, Carnival may ask for additional documentation such as a birth certificate or a letter of permission from a parent.

Bring original or certified copies of birth certificates for all children under 18, even if they also have a passport. Carnival may not accept photocopies. If a child is traveling with someone other than a parent—such as a grandparent, aunt, or family friend—bring a notarized letter from the parent giving permission for that person to travel with the child.

Frequently Asked Questions

Can a 17-year-old cruise with a friend's family instead of their own parents?

Yes, but you will need written permission from the teenager's parent or legal guardian. Bring a notarized letter stating that the parent allows the teen to travel with the other family. Carnival may also ask to see the teenager's birth certificate and the parent's ID to verify the relationship.

Do babies need a passport to cruise with Carnival?

It depends on where the ship is sailing. For cruises that visit only U.S. ports, a birth certificate is enough. For cruises that visit Caribbean islands or other countries, all passengers including infants need a valid passport. Check your specific itinerary with Carnival before booking.

Can a 20-year-old book a cabin alone if they are traveling with their 25-year-old sibling?

Yes. The 20-year-old can book their own cabin as long as the 25-year-old is also booked on the same cruise in a separate cabin. Both must be on the same reservation. The older sibling does not need to supervise the younger one, but both must be part of the booking.

What if my child gets sick or injured during the cruise?

Carnival ships have a medical center staffed with doctors and nurses. If your child needs care, go to the medical center or call your cabin phone and ask for medical information. There is a fee for medical services. Make sure your child has travel insurance that covers medical emergencies at sea.

Can teenagers leave the ship at ports without a parent?

Carnival's policy allows teenagers 13 and older to go ashore at ports without a parent if the parent signs a waiver. However, the parent is still responsible for the teenager's safety. Some ports are safer than others, and some activities are not recommended for unaccompanied minors. Discuss port safety with your teenager and decide together which ports they can explore alone.
