This marks the strongest early demand in the company’s history, with more bookings at this stage than any previous season on record.

The luxury operator has also announced a 150% uplift in trade revenue over the last two years, while its average booking value is now at £7,800.

Unforgettable Croatia has 144 guaranteed departures next year, across eight itineraries. The season runs from May to October on eight ships, each with a maximum of 19 cabins.

New for 2026 is a seven-night Opatija Hidden Gems itinerary on the 38-guest My Wish. Two departures will operate: the first on June 20, with a separate return sailing on June 27. This includes an optional guided tour of the Diocletian Palace and the Old Town of Split, before a transfer to Primosten to board the ship.

Most 2026 itineraries sail between Split and Dubrovnik along the Dalmatian coast, with an increasing number of departures from Sibenik. Ports of call include well-known favourites such as the medieval town of Trogir and Hvar, alongside lesser-known, hidden gems including Korcula, Vis and the national parks of Mljet and Krka.

Graham Carter, co-founder of Unforgettable Croatia, said: “We’ve seen a fantastic response to our 2026 programme, with travellers – both returning guests and new to the brand – keen to experience a holiday at sea with a difference. People are increasingly looking for a more personalised, immersive experience, where every journey feels uniquely tailored, and that is what an Unforgettable Croatia holiday delivers.

“I’d like to thank the trade for their hard work and dedication in helping more people discover the joys of small-ship cruising.”

All 2026 itineraries include luxury transfers, breakfast, three-course lunches and select dinners. A programme of guided tours and visits, daily swim-stops and complimentary use of all on board water sports, a professional cruise director and on-board lectures are also available.

Unforgettable Croatia offers seven-night cruises from £1,995pp, including breakfast, lunch, two dinners, private transfers, all excursions and Wi-Fi. Flights not included.
