Previously Virgin had only talked about weeklong cruises.
Earlier, the line announced it would sail to Cuba, and the 'Havana After Dark' four- and five-night itineraries feature an overnight stay there.
Overnight or late-night stays
Sailors will also have more time to explore in each place, with extended port hours and an overnight stay or a late-night sail away on all voyages.
Another destination TBA
Details about an additional destination for all sailings will soon be released.
'Our research with sailors unearthed their desire to go to places that allow for a variety of experiences,' said Diana Block Garcia, VP itinerary & destination for Virgin Voyages. 'Our destinations offer a combination of opportunities for exploration and relaxation, to complement our Virgin Voyages experience.'
