The operator also revealed the number of cabins sold increased by almost 7% year-on-year, while there was an overall average guest satisfaction score of 9.46 out of 10, based on 1,589 customer feedback responses collated across nine ships.
This represents the highest scores delivered for any season since Unforgettable Croatia launched in 2015.
Among the core fleet, Adris recorded the highest overall guest satisfaction score, at 9.64 out of 10, followed by Bellissima at 9.56 and My Wish at 9.55.
Graham Carter, co-founder of Unforgettable Croatia, said: “Finishing the season at more than 99% capacity, with cabin sales increasing year-on-year, is particularly encouraging.
"The feedback from our guests is equally impressive, with consistently high scores across all aspects of our luxury fleet. We'll use these insights to build on what's working well, identify further opportunities and ensure our 2027 programme continues to deliver the experiences our guests value most.”
Unforgettable Croatia's 2027 season will feature 140 sailings, operating from May to October, across 12 itineraries. Prices start from £1,842pp.
The season includes two new themed cruises: one has a local heritage focus, and the other food and wine. Four themed departures are on offer. Prices start from £2,310pp.
All itineraries include luxury airport transfers, daily breakfast, three-course lunches and select dinners, as well as a programme of guided tours and experiences. Guests also benefit from daily swim stops, complimentary use of onboard water sports equipment, the services of a professional cruise director and expert-led talks throughout the voyage.
In addition, Unforgettable Croatia has introduced an optional, complimentary Michelin Star reservation service on select cruises. The operator can book Michelin Star and Bib Gourmand restaurants to coincide with guests’ sailings, such as Restaurant 360 in Dubrovnik, Pelegrini in Šibenik and LD Restaurant in Korčula.
