Best Cruise Lines for Adults: Adult-Only & Adult-Friendly Cruises
Not every adult wants a cruise filled with waterslides, kids' clubs, and nonstop family activities.
Sometimes you want great food, good entertainment, interesting destinations, and a place to relax without feeling like you've wandered into summer camp at sea.
After more than 30 cruises, I've also learned that finding the best cruise for adults isn't as simple as choosing one cruise line. Your age, travel style, itinerary, ship, and even the length of the cruise can make a big difference.
Some cruise lines are especially popular with couples and mature travelers. Others are better for adults who want nightlife and a more energetic atmosphere. And if you truly want a cruise with no children onboard, your choices are much more limited.
Here's how they compare.
Are There Really Adults-Only Cruise Lines?
Yes, but there's an important difference between an adults-only cruise line and an adult-friendly cruise line.
Virgin Voyages is genuinely adults-only. Guests must be at least 18 years old to sail.
Celebrity Cruises, Holland America Line, Princess Cruises, Royal Caribbean, and Carnival are not adults-only cruise lines. Children can sail on them, although the atmosphere and number of families onboard can vary considerably depending on the ship, itinerary, time of year, and length of the cruise.
That distinction matters. If your goal is absolutely no children onboard, an adult-friendly cruise isn't the same thing as an adults-only cruise.
Does βAdults-Onlyβ Mean a Nude or Lifestyle Cruise?
No. An adults-only cruise simply means children are not permitted onboard. It does not mean the cruise is clothing-optional or intended for lifestyle travelers.
Nude and lifestyle cruises are specialty sailings, often organized as private charters, and are a separate category from mainstream adults-only cruises such as Virgin Voyages.
Virgin Voyages: Best for a Truly Adults-Only Cruise
If having no children onboard is your priority, Virgin Voyages is the obvious place to start.
Every guest must be at least 18, so the entire ship is designed around adults rather than having a few adult-only spaces within an otherwise family-friendly ship.
Virgin has a contemporary feel with distinctive restaurants, nightlife, entertainment, fitness and wellness activities, and plenty of places to socialize or relax.
It's especially appealing to adults who want something different from the traditional cruise experience.
A good fit for: Couples, groups of friends, younger adults, and anyone specifically looking for an 18+ cruise.

Celebrity Cruises: Best for a Modern, Upscale Adult-Friendly Cruise
Celebrity Cruises is not adults-only, but it has long appealed to adults who want a more sophisticated cruise without moving all the way into the luxury-cruise category.
The ships combine contemporary design, excellent dining, entertainment, spa experiences, and attractive accommodations with an atmosphere that tends to feel more grown-up than heavily family-focused cruise lines.
Celebrity can be especially attractive for couples who want a relaxing vacation but still want plenty to do in the evening.
A good fit for: Couples, empty nesters, mature travelers, and adults looking for a more upscale atmosphere.
Holland America Line: Best for a Quieter, More Relaxing Cruise
For adults searching for a relaxing or more laid-back cruise, Holland America deserves serious consideration.
The line is known for destination-focused itineraries, enrichment, live music and a more traditional style of cruising. Holland America does welcome families and operates a Kids Club for ages 3β17, so it should not be confused with an adults-only cruise line.
However, its overall cruise experience can appeal particularly well to mature travelers and adults who aren't looking for roller coasters, giant water parks, and an activity every five minutes.
Longer itineraries can make Holland America particularly attractive if your idea of a good vacation involves slowing down and actually enjoying being at sea.
A good fit for: Mature adults, couples, retirees, destination-focused travelers, and anyone looking for a quieter cruise experience.

Princess Cruises: Best for Couples Who Want Relaxation and Romance
Princess is another strong choice for adults who want a comfortable balance between activities and relaxation.
It's not an adults-only cruise line, but Princess offers experiences specifically geared toward adults, including The Sanctuary, its adults-only retreat.
Princess is also well suited to couples. You can spend the day exploring a port, enjoy dinner together, watch Movies Under the Stars, or simply sit on your balcony and watch the ocean go by.
It doesn't require you to choose between doing absolutely nothing and having something to do.
A good fit for: Couples, middle-aged and mature travelers, anniversary trips, and adults who want a relaxed traditional cruise.
Royal Caribbean: Best for Adults Who Still Want Plenty of Action
An adult cruise doesn't necessarily have to be quiet.
Some adults want shows, nightlife, restaurants and a huge variety of things to do. If that sounds more like your vacation, Royal Caribbean can still be a good choice even though it is one of the major family cruise lines.
The trick is choosing your sailing carefully.
I've found that longer cruises often feel very different from short cruises, regardless of the cruise line. Sail when school is in session and choose a longer itinerary, and the passenger mix may be quite different from what you'd encounter on a short school-break sailing.
Royal Caribbean makes the most sense here for adults who actually enjoy large ships and lots of entertainment rather than adults whose primary goal is avoiding families.
A good fit for: Active couples, groups of adult friends, and travelers who want entertainment and plenty of choices onboard.

Carnival: Best for Adults Who Want Fun and Value
Yes, Carnival can belong on a list of cruises for adults.
Carnival has a reputation as a family-friendly "fun ship" cruise line, and you'll certainly find families onboard. But that doesn't mean every Carnival cruise has the same atmosphere.
After more than 30 cruises, I've found that the length and timing of a cruise can matter almost as much as the name painted on the ship.
Longer Carnival itineraries often appeal to adults who have more flexibility in their travel schedules. Carnival also has its Serenity Adult-Only Retreat for guests 21 and older, although the rest of the ship remains family-friendly.
For adults who want a casual vacation, lively entertainment, and good value rather than a quiet upscale atmosphere, Carnival can make sense.
A good fit for: Fun-loving couples, groups of friends, budget-conscious travelers, and adults who prefer a casual cruise.
What Are the Best Cruises for Mature and Middle-Aged Adults?
There's no magic age at which one cruise line suddenly becomes the right choice.
A 35-year-old who wants peace, good food, and interesting destinations may be happier on the same ship as a 65-year-old looking for those things. Likewise, plenty of travelers in their 50s, 60s, and 70s would be bored silly on a cruise that's too quiet.
For mature or middle-aged adults who prefer a more relaxed atmosphere, I would look particularly closely at Celebrity, Holland America, and Princess.
If entertainment, nightlife and lots of onboard activities matter more, Royal Caribbean or Carnival may be a better match.
And if the most important requirement is an entirely child-free ship, Virgin Voyages is the standout among the lines covered here because its sailings are restricted to guests 18 and older.
What Are the Most Relaxing Cruise Lines for Adults?
If relaxation is the goal, don't look only at the cruise line.
The itinerary can dramatically change the experience.
A longer sailing with several sea days can feel completely different from a three-night getaway. Cruises outside major school holidays may also have a different passenger mix than summer and spring-break sailings.
For a calmer vacation, consider:
A longer itinerary
Fewer packed port days
Traveling outside major school holidays
A ship with dedicated adult relaxation areas
An itinerary that matches the pace you actually enjoy
Holland America, Celebrity, and Princess are good places to begin looking for this style of cruise, but the individual ship and itinerary still matter.
What Are the Most Fun Cruises for Adults?
If your definition of an adult vacation includes nightlife, entertainment and meeting people rather than reading quietly by the pool, look at a different group.
Virgin Voyages offers the advantage of an entirely 18+ environment along with nightlife and entertainment designed for adults.
Royal Caribbean offers enormous ships with extensive entertainment and activities, while Carnival provides a casual, lively atmosphere that can work especially well for groups of friends and couples who aren't looking for a formal cruise.
Being an adult doesn't automatically mean wanting a quiet ship. Pick the atmosphere that sounds fun to you.
Are There 21+ Cruises?
This is where the terminology can get confusing.
An adult-only area on a ship is not the same thing as an adults-only cruise.
For example, Carnival's Serenity Adult-Only Retreat is restricted to guests 21 and older, but Carnival ships themselves are not 21+. Children and teenagers can sail elsewhere on the ship.
Virgin Voyages, meanwhile, is adults-only across the entire ship, but its minimum sailing age is 18 rather than 21.
So if you specifically want a 21+ cruise, check the current age policy for the particular cruise or experience you're considering rather than assuming "adults-only" automatically means 21 and older.
How to Choose the Best Cruise for Adults
One of the biggest lessons I've learned after more than 30 cruises is that the itinerary can be just as important as the cruise line.
Before booking, think about what you actually want your vacation to feel like.
Do you want peace and quiet or late-night entertainment? Do you want an entirely child-free ship, or would an adults-only retreat be enough? Are you cruising primarily for the ship, or are the destinations the most important part of the vacation?
And don't overlook cruise length.
A short weekend cruise during a school holiday can have a completely different atmosphere from a longer sailing on the very same cruise line.
That's why I wouldn't choose a cruise based solely on somebody else's idea of the "best" cruise line. Choose the combination of cruise line, ship, itinerary and sailing date that fits the vacation you actually want.
Ready to Find Your Cruise?
There isn't one cruise line that's perfect for every adult traveler.
Virgin Voyages offers a genuinely adults-only 18+ experience. Celebrity, Holland America and Princess can appeal to adults looking for a more relaxed or refined vacation. Royal Caribbean and Carnival may be better suited to adults who want more activity, entertainment, or a casual atmosphere.
Once you know which experience sounds most like you, compare itineraries and prices before deciding.
