Azamara Club Cruises is expanding coverage of Cuba with new 2018 and 2019 itineraries.
The sailings range from four to 14 nights and visit Cuban ports like Cienfuegos, a UNESCO World Heritage Site.
Two overnights in Havana and longer stays in port have been scheduled.
Three new night-time shore excursions have been added together with more small-group trips to introduce passengers to the culture and people of Cuba in the most authentic way, according to the small ship line.
President and CEO Larry Pimentel said: “Following the incredible popularity and high demand for our Cuba voyages, we knew we wanted to provide travellers more opportunities to explore this alluring country at night.
“We’re fully committed to exceptional on-shore exploration through our longer stays in port.
“With more overnights and night tour programming, it makes sense that we would be one of the few ships to offer three full days in Havana.”
