On January 30, 2026, Ambassador Cruise Line's Ambience left Tilbury on the Thames for a 40-night loop of the Caribbean. Thirteen hours of that voyage, on February 16, were spent alongside in Havana. No other mainstream cruise ship called at the Cuban capital in 2026. For a modest British cruise line running a 35-year-old ship, that is a quietly impressive thing to have pulled off.
The itinerary
The "Jewels of the Caribbean Sea" sailing is the sort of trip that only makes sense if you do not have to fly. The ship crossed the Atlantic by way of Ponta Delgada in the Azores, then worked through the islands: Antigua, Tortola in the British Virgin Islands, Havana, George Town in the Cayman Islands, Santo Domingo, Fort-de-France, Montego Bay and Ocho Rios in Jamaica, Bridgetown in Barbados, and Castries in St. Lucia, before turning for home.
Forty nights sounds like a lot. For Ambassador's guests, mostly retired, mostly British, often traveling as couples, it is the format they ask for. The line reported that longer itineraries were among the fastest sellers at its record 2026-27 launch, and it has leaned in: next season brings a 45-night Caribbean Adventure that adds Mexico and Colombia, and a 42-night Gems of the Caribbean Sea.
Why Havana
Cuba has been on and off the cruise map for a decade. American lines were barred from calling after 2019, and the island's cruise traffic collapsed. European lines face no such restriction, but few have bothered to go back; Cuba's ports lack the infrastructure and shore-excursion machinery that large ships depend on.
Ambience is the right size for it. At around 70,000 tons and 1,400 guests, she is small enough to berth in Havana's harbor and big enough to carry a full program of entertainment across a 40-night voyage. A 13-hour call gives guests a proper day: time for a vintage-car tour, the old town, a late lunch and a stroll along the Malecón before sailing. That is more than most single port days offer anywhere.
It also says something about how Ambassador plans itineraries. The line's 2026-27 program lists 27 ports that are new to it, and the company has made a habit of favoring places the big ships skip, whether that is Havana, Honfleur or Kirkwall. For a repeat guest who has been to Barbados three times already, that is the difference between booking and not.
The ship behind it
Ambience started life in 1991 as Princess Cruises' Regal Princess, one of a pair of Renzo Piano-designed ships with a distinctive domed forward lounge. She later sailed for P&O Australia as Pacific Dawn before Ambassador bought her in 2021 and made her the line's flagship. She came out of a three-week drydock in the UK early in 2026, shortly before this voyage.
Nobody at Ambassador markets her as cutting-edge. What they market is a ship with wide outdoor decks, a proper theater, several restaurants, and a crew that gets consistently warm reviews. The company's own figure is that 94% of guests would recommend the line to a friend, and more than half of bookings at the last launch came from people who had sailed before. Long cruises are where loyalty like that gets built. Forty nights with the same tablemates and the same bar staff turns a holiday into something closer to a community.
What's next for Ambience
After the Caribbean, Ambience returned to her bread-and-butter program of British Isles, Norway, Iberia and Baltic sailings from London and other UK ports. In early November she sets off on a 31-night Mediterranean voyage, roundtrip from Tilbury, with calls across North Africa, Sicily and the Adriatic. And in December she becomes a floating venue for Ambassador's festive lunches, dinners and overnight stays at the London Cruise Terminal, for people who want a bit of ship life without going anywhere.
Ambassador is also working with the marine conservation charity ORCA, whose observers are spending 200 days at sea on the line's ships in 2026 counting whales and dolphins. On a transatlantic crossing, that is a bonus: a guest lecture from someone who actually spotted a fin whale off the Azores that morning.
If a 40-night cruise from the Thames to Havana and back sounds like your kind of trip, Ambassador is now one of the very few companies offering it. Book early; the long ones go first.
