(11:25 a.m. EST) -- Norwegian Cruise Line will expand its offerings in Cuba with new sailings aboard Norwegian Sun.

This fall, cruisers can board Norwegian Sun in Miami for one of six weeklong cruises (every Sunday from September 9 through October 14, 2018) with calls in Great Stirrup Cay, Costa Maya, Harvest Caye (Norwegian's privately developed port in Belize) and of course, Havana.

Norwegian's nine-night Cuba and Caribbean itinerary also includes calls in Roatan and Cozumel.

An extended 13-night sailing departs Miami on October 30 and heads through the Panama Canal to Havana, Harvest Caye, Roatan, Puerto Limon, Colon, Cartagena, Santa Marta and Aruba.

Those short on time can see Cuba in five days with a September 3 sailing from Port Canaveral in Orlando that will call on Key West before heading to Havana for an overnight stay, and finishing out the cruise with a stop at the line's private island in the Bahamas, Great Stirrup Cay.

"We are thrilled to reveal Norwegian Sun's new fall 2018 itineraries, which will be the first time our brand has featured a call in Havana, Cuba on seven-day and longer cruises," said Andy Stuart, president and CEO of Norwegian Cruise Line in a news release. "These new itineraries offer a remarkable breadth of experiences for guests with a culturally immersive full day and evening in Havana, complemented by several visits to world-class destinations across the Caribbean and beyond."

While in port, passengers on a Norwegian cruise to Cuba have a selection of 13 half- and full-day shore excursions that are compliant with government regulations. These include a farm-to-table dining experience or a tour of modern-day Cuba in a class American car.

Norwegian already offers four-night Cuba cruises onboard Norwegian Sky from Miami and Port Canaveral.
