The drinking age on most cruises is 21, even if you are 18
If you are 18 and planning to cruise, you will not be able to order alcohol at the bar, in your cabin, or at restaurants on most cruise ships. The major cruise lines — Carnival, Royal Caribbean, Disney, and Norwegian — all enforce a minimum drinking age of 21, regardless of where the ship is sailing or what the legal drinking age is in other countries.
This rule applies even when the ship is in international waters or docked at ports where the legal drinking age is lower. The cruise line's policy overrides local law. If you try to purchase alcohol and are under 21, the bartender or server will ask for a government-issued ID. If your ID shows you are under 21, they will refuse the sale.
Some smaller cruise lines and specialty operators may have different policies, but you should assume 21 is the standard unless you contact the cruise line directly before booking.
Key Takeaways
- All major cruise lines require you to be 21 to purchase or consume alcohol, even if you are 18 years old.
- This age restriction applies everywhere on the ship and at every port, regardless of local drinking laws.
- Bringing your own alcohol into your cabin is prohibited, and crew members will confiscate it during embarkation.
- Some cruise lines offer beverage packages that include alcohol, but you must be 21 to use them.
- A few specialty or smaller cruise operators may have different policies, so contact the cruise line before you book if the drinking age matters to your trip.
Why cruise lines enforce 21 as the drinking age
Cruise ships registered in the United States operate under U.S. federal maritime law, which sets 21 as the drinking age. Even if a ship sails from a U.S. port and returns to a U.S. port, the ship itself is considered U.S. territory while at sea. This means U.S. drinking laws explore on board.
Cruise lines also enforce this rule to reduce liability and maintain safety. A uniform age policy across all ships and all sailings is simpler to enforce than trying to track which passengers are in which countries at which times. It also protects the cruise line from lawsuits if an underage passenger is injured or causes injury to others while intoxicated.
The policy is printed in the cruise line's terms and conditions, which you agree to when you book. Violating it can result in being removed from the ship at the next port without a refund.
What happens if you try to bring alcohol on board
Most cruise lines allow you to bring a limited amount of alcohol into your cabin — typically one bottle of wine or champagne per person, sealed and unopened. However, this rule applies only to passengers who are 21 or older. If you are 18, you cannot bring alcohol on board at all.
During embarkation, crew members conduct security checks and will confiscate any alcohol they find in your luggage or on your person. You will not get it back. If you attempt to sneak alcohol on board and are caught, you may be denied boarding or removed from the ship.
Some cruise lines are stricter than others. Norwegian Cruise Line, for example, allows one bottle per stateroom for passengers 21 and up. Carnival and Royal Caribbean have similar policies. Disney Cruise Line does not allow any alcohol to be brought on board by passengers, regardless of age.
Beverage packages and what you can order at 18
Many cruise lines sell beverage packages that include unlimited alcoholic drinks. These packages are available only to passengers 21 and older. If you are 18, you cannot purchase a beverage package that includes alcohol, and you cannot use someone else's package to order drinks.
At 18, you can order non-alcoholic beverages at any bar or restaurant on the ship. This includes sodas, juices, coffee, tea, and specialty non-alcoholic drinks. You can also order water, which is free. Some cruise lines offer virgin versions of popular cocktails — drinks with the same flavors and presentation but without the alcohol — and these are available to passengers of any age.
If you are traveling with family members who are 21 or older, they can order alcohol for themselves, but they cannot order it for you or give you their drinks.
Ports and international waters
The drinking age restriction does not change when the ship is docked at a port, even if that port is in a country where the legal drinking age is lower than 21. For example, if your cruise stops in Mexico or the Caribbean, where the drinking age may be 18, you still cannot order alcohol on the ship itself.
Once you leave the ship and go ashore at a port, you are subject to that country's laws. If the local drinking age is 18, you may be able to purchase alcohol at a bar or restaurant in that port. However, you cannot bring alcohol back on board the ship. Crew members will confiscate it during re-boarding.
Some passengers attempt to drink at ports and then return to the ship intoxicated. Cruise lines have policies against boarding intoxicated passengers, and crew members can refuse to let you back on the ship if they believe you are too drunk. This could result in being left behind at that port.
Exceptions and specialty cruise lines
A small number of cruise operators outside the major cruise lines may have different policies. Some river cruises, expedition cruises, or charter cruises may allow passengers under 21 to consume alcohol in limited circumstances or with parental consent. However, these are rare exceptions.
If you are booking a cruise with a smaller operator or a specialty cruise line, contact them directly to ask about their drinking age policy. Do not assume it is 21 just because the major lines enforce that age. Get the policy in writing before you book and pay.
Some cruise lines also offer family-friendly sailings or youth programs where alcohol is restricted or not served at all, regardless of passenger age. These are marketed specifically as alcohol-free or family-focused experiences.
What to do if you are 18 and want to cruise
Being 18 does not mean you cannot enjoy a cruise. Many activities on cruise ships do not involve alcohol: dining, entertainment, swimming, fitness classes, shore excursions, casino games (if you are 18 and the ship allows it), and deck activities are all available to you.
If drinking is important to your trip, you have a few options. You can wait until you are 21 to cruise. You can cruise now and focus on the non-alcoholic activities and experiences. Or you can cruise to a destination where you can drink legally at ports, as long as you understand the ship's re-boarding rules.
Talk to the cruise line before you book if you have questions about their specific policies. Their customer service team can answer questions about what is and is not allowed for passengers under 21.
Frequently Asked Questions
Can my parent or guardian buy alcohol for me on the cruise?
No. Cruise lines prohibit adults from purchasing alcohol for anyone under 21, including their own children. If a crew member observes this, they can confiscate the drink and may ask the adult to leave the ship at the next port.
What if I use a fake ID to order alcohol?
Using a fake ID on a cruise ship is a federal crime because the ship is considered U.S. territory. You could face criminal charges, be removed from the ship without a refund, and be banned from future cruises. The risk is not worth it.
Can I drink alcohol in my cabin if I am 18?
No. The age restriction applies everywhere on the ship, including your cabin. If crew members find alcohol in your room and you are under 21, they will confiscate it. You cannot consume alcohol in your cabin at any age under 21.
Do all cruise lines have the same drinking age policy?
Most major cruise lines enforce 21 as the minimum drinking age. Some smaller or specialty cruise operators may have different policies. Contact the cruise line directly to confirm their policy before you book.
Can I buy alcohol at a port and bring it back on the ship?
No. Crew members will confiscate any alcohol you try to bring on board during re-boarding, regardless of your age or where you purchased it. This rule applies to all passengers.
