What Cruise Line Can You Drink at 18 Find Out Here

Most cruise lines require passengers to be 21 to drink alcohol, but a few, like Royal Caribbean and Norwegian Cruise Line, allow guests as young as 18 to consume alcohol—when sailing from Europe or select international ports. This age exception applies only to specific itineraries and not within U.S. waters due to federal law. Always check the cruise line’s official alcohol policy before booking to avoid surprises at sea.

Key Takeaways

• Norwegian Cruise Line allows drinking at 18 in international waters.
• Check destinations—some ports enforce local drinking ages.
• Parental consent may be required for under-21 passengers.
• Royal Caribbean and Carnival maintain a strict 21+ policy.
• Always carry ID to verify age onboard and ashore.
• Review policies before booking to avoid surprises.

What Cruise Line Can You Drink at 18? Find Out Here

Imagine this: you’re 18 years old, standing on the deck of a luxury cruise ship, the sun setting over the ocean, a refreshing cocktail in hand. For many young adults, this vision is a dream—but is it a reality? If you’re 18 and looking forward to your first cruise, you might be wondering: what cruise line can you drink at 18? The answer isn’t as simple as a yes or no. While most cruise lines follow the U.S. legal drinking age of 21, there are exceptions, particularly when sailing internationally or under specific circumstances.

Alcohol policies on cruise ships are shaped by a mix of U.S. maritime laws, international regulations, and the policies set by individual cruise lines. For 18-year-olds, the opportunity to drink legally onboard often depends on the itinerary, the home country of the cruise line, and whether the ship is in international waters or docking in a country with a lower drinking age. This blog post dives deep into the world of cruise ship alcohol policies to answer the burning question: which cruise lines allow 18-year-olds to drink? Whether you’re planning a solo trip, a graduation celebration, or a family cruise, this guide will equip you with the knowledge to make informed decisions and avoid any unwelcome surprises at the bar.

Understanding Cruise Line Alcohol Policies: The Legal Framework

The first step in answering “what cruise line can you drink at 18” is understanding the legal and regulatory landscape that governs alcohol consumption on cruise ships. Unlike land-based venues, cruise ships operate in a unique legal gray area, navigating between national laws, international waters, and the internal policies of each cruise line.

U.S. vs. International Drinking Age Laws

In the United States, the legal drinking age is 21, and this law applies to all U.S.-based cruise lines—regardless of where the ship is sailing. However, when a cruise ship enters international waters (typically beyond 12 nautical miles from shore), it is governed by the laws of the country where the ship is registered (its “flag state”). For example, a Carnival cruise ship, registered in Panama, follows Panamanian maritime law, which has a drinking age of 18. This creates a loophole: while the ship may enforce a 21+ rule in U.S. ports, the legal drinking age in international waters could technically be lower.

That said, most major U.S.-based cruise lines choose to maintain a uniform 21+ policy across all itineraries to avoid confusion, liability, and to comply with U.S. Department of Transportation regulations. However, there are exceptions—especially on transatlantic or European itineraries where the ship spends most of its time outside U.S. jurisdiction.

Flag States and Their Influence

Here’s a breakdown of common flag states and their drinking ages:

• Panama: 18
• Liberia: 18
• Marshall Islands: 18
• Malta: 17 (with parental consent)
• United Kingdom (for some lines): 18

While these are the legal ages in those countries, cruise lines often adopt stricter internal policies. For example, Royal Caribbean, registered in the Bahamas, still enforces a 21+ drinking age on most U.S.-departing cruises, even though Bahamian law allows drinking at 18. The key takeaway: legal age ≠ cruise line policy.

When the Ship Is in International Waters

Once a ship crosses into international waters, it is no longer subject to U.S. state laws. This is where things get interesting. Some cruise lines use this to their advantage by allowing 18-year-olds to drink only when the ship is outside U.S. territorial waters. This policy is often applied on longer voyages, such as transatlantic crossings, repositioning cruises, or European itineraries. For example, a 7-day cruise from Miami to Barcelona may allow 18-year-olds to drink after the ship leaves U.S. waters—typically within 24–48 hours of departure.

However, this policy is not universal. It requires careful planning, and passengers must be prepared to show ID and sign waivers. It’s also important to note that alcohol consumption is still monitored—excessive drinking is not permitted, and staff can refuse service at any time.

Cruise Lines That Allow Drinking at 18: The Exceptions

Now that we understand the legal framework, let’s explore the cruise lines that do allow 18-year-olds to drink under certain conditions. These are the exceptions to the 21+ rule, and they often depend on the itinerary, the ship’s flag, and the cruise line’s internal policies.

Royal Caribbean International

Royal Caribbean is one of the most well-known cruise lines that allows 18-year-olds to drink—but only on select international itineraries. According to their official policy, guests aged 18–20 can consume beer and wine only when the ship is outside U.S. territorial waters. This typically applies to:

• Transatlantic cruises
• Repositioning voyages (e.g., from Florida to Europe)
• European sailings (e.g., Mediterranean, Baltic)

On these cruises, 18-year-olds can enjoy beer, wine, and champagne at bars, restaurants, and lounges. However, hard liquor (spirits, cocktails with spirits) is still restricted to those 21 and over. To access these benefits, guests must:

• Show a valid government-issued ID
• Sign a waiver acknowledging the policy
• Be aware that the policy only applies during specific segments of the cruise

Example: A 21-year-old and an 18-year-old sibling on a 10-day transatlantic cruise from Miami to Southampton. After the ship leaves U.S. waters (around Day 2), the 18-year-old can order a glass of wine at dinner or a beer at a poolside bar. But if they order a rum and coke, it will be denied.

Norwegian Cruise Line (NCL)

NCL follows a similar policy to Royal Caribbean. Guests aged 18–20 can consume beer and wine only on international itineraries outside U.S. waters. This includes:

• European cruises
• Transpacific voyages
• World cruises

NCL’s policy is more flexible in practice. Some guests report being served cocktails with spirits on European cruises, especially if they are with family or on a private event. However, this is at the discretion of the bar staff and not a guaranteed policy. NCL also offers “Beer & Wine Packages” that 18-year-olds can purchase on eligible cruises.

Celebrity Cruises

As a subsidiary of Royal Caribbean, Celebrity Cruises follows nearly identical alcohol policies. 18-year-olds can drink beer and wine on international itineraries outside U.S. waters. Celebrity is known for its upscale, adult-focused atmosphere, so the policy is often more strictly enforced. That said, the experience is smoother for young adults on European or transatlantic sailings.

MSC Cruises

MSC Cruises, an Italian-based line registered in Switzerland, has a more lenient approach. Since the ship’s flag state and home country have a drinking age of 18, MSC allows 18-year-olds to consume all types of alcohol—including spirits—on all cruises, regardless of itinerary. This is a significant advantage for young travelers.

MSC’s policy is straightforward: if you’re 18 or older, you can order any drink on the menu. This includes cocktails, wine, beer, and premium spirits. However, passengers must still show ID, and excessive drinking is monitored. MSC is particularly popular in Europe, where the cultural norm is for younger adults to enjoy alcohol in moderation.

Tip: If you’re 18 and planning a European cruise, consider booking with MSC. You’ll have full access to the bar scene without the hassle of territorial water rules.

Itineraries Matter: Where and When You Can Drink at 18

Even on cruise lines that allow drinking at 18, the itinerary is the deciding factor. Not all cruises are created equal when it comes to alcohol policies. Here’s how to choose the right sailing to maximize your drinking eligibility.

Transatlantic and Repositioning Cruises

These long-haul voyages are ideal for 18-year-olds. Ships spend 7–14 days at sea, crossing the Atlantic or Pacific, which means they are in international waters for the majority of the trip. On Royal Caribbean, NCL, and Celebrity, this triggers the 18+ beer and wine policy. Some guests even report being served cocktails after a few days at sea, though this is not guaranteed.

Example: A 14-day transatlantic cruise from Miami to Rome (Royal Caribbean). Days 3–12 are in international waters, so the 18-year-old can enjoy wine with dinner and beer at the pool bar. On Day 13, when the ship enters Italian waters, the policy remains in effect since Italy’s drinking age is 16 for wine and beer (18 for spirits).

European Cruises (Mediterranean, Baltic, Northern Europe)

European itineraries are goldmines for 18-year-olds. Most ports have drinking ages between 16 and 18, and the cruise lines adapt their policies accordingly. On Royal Caribbean, NCL, and Celebrity, the 18+ rule applies as soon as the ship leaves U.S. waters. On MSC, it applies from Day 1.

Tip: Book a cruise that departs from a European port (e.g., Barcelona, Southampton, Rome). This eliminates the need to cross U.S. waters, meaning you can drink from the start—even on U.S.-based lines like Royal Caribbean.

World Cruises and Extended Voyages

World cruises (e.g., Royal Caribbean’s 6-month “Ultimate World Cruise”) are another great option. These sailings spend months in international waters and visit countries with lower drinking ages. On such cruises, the 18+ policy is often relaxed, and staff may allow 18-year-olds to order cocktails, especially if they are with family or in a private setting.

What Doesn’t Work: U.S.-Based Short Cruises

Unfortunately, short cruises from U.S. ports (e.g., 3–5 days to the Bahamas or Mexico) do not qualify for the 18+ policy. These ships typically remain within U.S. territorial waters for the entire trip, so the 21+ rule applies. Even if the ship docks in a country with a lower drinking age (e.g., the Bahamas, where it’s 18), the cruise line’s internal policy usually overrides local laws.

Example: A 4-day Carnival cruise from Miami to Nassau. Despite the Bahamas’ 18+ drinking age, Carnival enforces a 21+ rule onboard. The only way to drink legally at 18 is to go ashore and visit a local bar—but you’ll need to be cautious about returning to the ship.

How to Prepare: Tips for 18-Year-Olds on Cruise Vacations

Knowing the rules is just the first step. To make the most of your cruise—especially if you’re 18 and hoping to drink—you need a strategy. Here are practical tips to ensure a smooth and enjoyable experience.

Verify the Policy Before Booking

Don’t assume. Always check the cruise line’s official website or contact customer service to confirm their alcohol policy for your specific itinerary. For example:

• Royal Caribbean’s policy: “Guests 18–20 may consume beer and wine only on international itineraries outside U.S. waters.”
• MSC’s policy: “Guests 18 and over may consume all types of alcohol on all cruises.”

Ask: “Does the 18+ policy apply on this cruise, and if so, from which day?”

Bring the Right ID

You’ll need a government-issued photo ID (e.g., driver’s license, passport) to prove your age. Cruise lines are strict about this, especially in U.S. ports. A school ID or birth certificate won’t cut it.

Sign Waivers (If Required)

On cruise lines like Royal Caribbean, 18-year-olds must sign a waiver acknowledging the alcohol policy. This usually happens at check-in or during the muster drill. Don’t skip this step—otherwise, you won’t be allowed to order alcohol.

Be Discreet and Respectful

Even if you’re legally allowed to drink, avoid excessive consumption. Cruise staff monitor alcohol intake, and if you appear intoxicated, they can refuse service. Also, be respectful of other passengers—especially families and seniors. The cruise line wants everyone to have a good time, and rowdy behavior could get you banned from the bar.

Consider Alternative Activities

Not all fun revolves around alcohol. Many cruise lines offer exciting non-alcoholic options:

• Mocktail bars (e.g., Virgin Voyages’ “No Loitering” bar)
• Escape rooms, arcades, and game lounges
• Shows, live music, and dance clubs
• Sports complexes and water parks

If you’re on a U.S.-based short cruise where drinking at 18 isn’t allowed, focus on these activities. You’ll still have a blast—and avoid any legal issues.
