Just over 1.8 million cruise visitors arrived in Grand Cayman last year, a decline of nearly 5%.
The figure, 1,831,011, is still the third-best year for cruise arrivals on record.
The 2018 total of 1.92 million passenger arrivals, bolstered by ships diverted from hurricane-hit countries in the eastern Caribbean, was the highest ever.
Representatives of Royal Caribbean have indicated that numbers could surge beyond 2.5 million if Cayman builds a cruise berthing facility. Opponents have suggested that would be more visitors than the island could handle.
