The main adults-only cruises from the UK in 2026 and 2027 are P&O Cruises’ Aurora and Arcadia from Southampton (18 and over), Saga’s Spirit of Discovery and Spirit of Adventure from Dover (over-50s), and Viking’s ocean ships on selected sailings from Greenwich in London (18 and over). Virgin Voyages has stopped sailing from Portsmouth for 2027, and Marella’s adults-only ships are fly-cruises from UK airports rather than ex-UK sailings.

That is the short answer, but the details have shifted a lot in the past year. P&O now carries families on some Aurora and Arcadia holidays, Arcadia is leaving the fleet in 2029, and Virgin has pulled out of UK ports. This guide focuses on child-free cruises you can join without flying, explains which sailings to watch out for, and covers the British-favourite lines that feel adult even though they accept children.

P&O Cruises: adult only cruises from Southampton
For most British passengers, P&O is the first name that comes up, because it is the only big mainstream line with dedicated adults-only ships sailing round-trip from Southampton. Both ships are for guests aged 18 and over on their standard sailings, and both feel distinctly British, with pubs, afternoon tea, ballroom dancing and a quieter pace than the line’s large family ships, Iona and Arvia. If you are weighing up the whole fleet, our comparison of the best P&O Cruises ship for you sets Aurora and Arcadia against the newer ships.
Aurora
Aurora is the smallest ship in the P&O fleet, carrying around 1,900 guests. That size suits classic itineraries such as Norway, Iceland, the Baltic, the Mediterranean and short breaks to Belgium, the Netherlands and Guernsey. She has three pools, one with a retractable roof that is handy on a northern European itinerary, along with a cinema and plenty of small lounges.
Arcadia
Arcadia is slightly larger, with space for a little over 2,000 guests, and tends to run longer voyages, including P&O’s annual world cruise departing in January. Her shorter sailings include the Norwegian fjords, the British Isles and Iceland, and the Canary Islands.
What is changing on P&O’s adult ships
Two changes are worth knowing before you book:
- Some sailings now welcome families. From December 2026 P&O opened selected Aurora and Arcadia holidays to all ages, mainly around Christmas, New Year and the 2027 school summer holidays. Examples include Aurora’s 11 December 2026 short break to Rotterdam and 15 December 2026 Christmas Scandinavia cruise, and Arcadia’s 21 December 2026 Christmas sailing to Spain, Portugal and the Canaries. There are no kids’ clubs on these sailings, but if a child-free holiday is the point, check the age policy of your specific date.
- Arcadia is leaving. Arcadia’s farewell season runs until she transfers to Holland America Line in August 2029. Cunard’s Queen Anne is due to join P&O the same year after a refit and renaming, but at the time of writing P&O has not said whether she will be adults-only.
Outside those family sailings, both ships remain adults-only for most of the year, so it is still easy to find a child-free P&O cruise from Southampton in term time, spring and autumn.
Saga: over-50s cruises from Dover
Saga is not adults-only in the 18-plus sense, but it is even more grown-up: cruises are for people aged 50 and over, and a travelling companion can be 40 or over. The line has two boutique ships, Spirit of Discovery (2019) and Spirit of Adventure (2021), each carrying fewer than 1,000 guests, and almost every cabin has a balcony.
The big draw is how much is included. Fares typically cover a chauffeur to the port (within a set distance) or port parking, drinks including wine, beer, cocktails and spirits, all onboard gratuities, Wi-Fi and speciality dining. Most UK sailings leave from Dover, and 2027 marks Saga’s 30th year of ocean cruising, with anniversary sailings in May 2027, including a British Isles voyage from Dover on Spirit of Discovery.
Prices reflect the inclusions. As an example, an eight-night Norway sailing from Dover in September 2027 was listed from around £3,700 per person in a balcony cabin at the time of writing. That looks high next to P&O, but the gap narrows once you add drinks, tips, parking and Wi-Fi to a mainstream fare.
Viking: child-free sailings from London
Every Viking ocean ship is for guests aged 18 and over, and the line’s style is calm and understated, with no casino, no kids’ facilities and no extra charge for the thermal suite in the spa. Viking’s ships carry fewer than 1,000 guests.
Viking is not a Southampton line, but it does run selected sailings from Greenwich in London, including British Isles itineraries and longer Scandinavian and Viking Shores voyages in 2027. Fares usually include a shore excursion in each port, Wi-Fi, speciality restaurants and wine or beer with lunch and dinner. It is a good choice if you want a no-fly, adults-only cruise built around the destinations rather than the entertainment.
Virgin Voyages: no UK sailings in 2027
Virgin Voyages is adults-only across its fleet (18 and over) and has a livelier, younger feel than the other lines here. It ran summer seasons from Portsmouth for several years, but the last of these departures were on Valiant Lady in August 2026. Its 2027 programme focuses on the Mediterranean instead, so British guests now need to fly to join a sailing.
Virgin’s fares include all restaurants except one tasting-menu venue, basic drinks such as soft drinks and tea, Wi-Fi and tips. If Virgin brings back UK departures in a future season, it will once again be the most modern adults-only ship sailing from a British port. For now, it is a fly-cruise option.
TUI and Marella adults-only cruises
Marella, TUI’s cruise line, is a popular choice for British adults who want sunshine and drinks included. Marella Explorer 2 is adults-only all year, Marella Discovery was adults-only for summer 2026, and Marella Discovery 2 becomes a permanent adults-only ship from winter 2027, with its former kids’ areas being turned into spaces such as a speakeasy, an escape room and a karaoke room. The minimum age is 17.
The catch for anyone searching for TUI adults-only cruises from Southampton is that Marella mainly sells fly-cruises: flights from UK regional airports and transfers are part of the package, and the ships are based in places such as the Canary Islands, the Mediterranean and Barbados. Fares are all-inclusive as standard, covering meals, most drinks and tips, with extra charges for premium venues and the spa.
Lines that feel adults-only but aren’t
Some British-favourite lines accept children but, in practice, attract a mostly older crowd and very few families outside school holidays. These can be good alternatives if you want a quiet ship from a UK port on a date the adults-only ships don’t cover.
- Fred. Olsen Cruise Lines sails smaller ships from a range of UK ports, often on no-fly itineraries to Norway, the Canaries and the British Isles. It is not adults-only, but children are rare outside the holidays.
- Ambassador Cruise Line sails from London Tilbury and other UK ports with mid-sized ships aimed at older British cruisers. It is not adults-only either, so check the age mix of your chosen dates.
- Cunard sails from Southampton and has a formal, grown-up atmosphere, though its ships do have facilities for children.
If you are travelling in term time, the atmosphere on these ships can be very similar to an adults-only cruise, and the itineraries are often just as appealing.
How to pick the right adults-only cruise from the UK
A few practical points help narrow the choice:
- Decide whether you want to fly. If you want to drive to the port, focus on P&O from Southampton, Saga from Dover and Viking from Greenwich. Virgin and Marella now mean a flight.
- Check the age policy of the exact date. This matters most on Aurora and Arcadia, where family sailings now cluster around Christmas, New Year and the summer holidays.
- Compare the real cost. Add drinks, tips, Wi-Fi and parking to a P&O fare before comparing it with Saga or Viking, which include most of those things.
- Match the ship to the trip. No-fly winter trips are especially popular; our guides to Northern Lights cruises from the UK and Norwegian fjords cruises from the UK cover the sailings in more detail, many of them on the ships above.
- Watch for offers. Fares change constantly, and launch sales and early booking deals can make a big difference. Our roundup of cruise deals for 2027 explains when to book.

Minimum ages vary a lot between lines, so see our rundown of cruise lines that accept 18-year-olds before booking.
