'We have already seen terrific results with our 2019 Cuba sailings with a response beyond our expectations,' said Colby Goodman, VP marketing, SeaDream Yacht Club. 'Many of our bookings so far have come from past guests eager to see Cuba for the first time.'
After an initial sale period available only to past passengers, the cruises are now open for booking by the general public. SeaDream said very limited availability remains.
Fares for the seven-day voyages start at $5,399 plus fees.
Due to strong demand a ninth departure was added, leaving from Cienfuegos on March 4, 2019.
SeaaDream ports include Cabo Cruz, founded in the early 18th century on the western edge of Granma Province in southern Cuba. Cayo Largo, an intimate resort island, has pristine beaches like Playa Sirena and Playo Paraíso.
Isla de Juventud, is popular with divers and rich in pirate lore. Black-sand beaches line the island's striking turquoise waters.
Maria la Gorda, accessible only to smaller vessels, offers a lush landscape that's home to many species of wildlife and is popular with scuba divers and snorkelers.
Santiago de Cuba, the country's second largest city, dates to the 16th century and is home to the citadel of San Pedro de la Roca, a UNESCO World Heritage Site. Trinidad, another UNESCO World Heritage Site, is a well-preserved Spanish settlement from the 16th century.
