Yes, you can cruise to the Caribbean directly from Southampton in 2026, though these are typically longer, "Transatlantic" voyages. Because the distance is over 4,000 miles, these itineraries usually last between 21 and 35 days. Lines like Cunard (on the Queen Mary 2), P&O Cruises, and Princess Cruises offer seasonal departures, often in late autumn or early spring, as ships "reposition" between the UK and the Caribbean. A typical voyage starts with 6 to 7 days at sea crossing the Atlantic, followed by visits to islands like Barbados, Antigua, and St. Lucia, before either flying back to the UK or sailing all the way back. These cruises are a favorite for those who dislike flying and want to experience the "Old World" luxury of a long sea voyage, often featuring a ratio of one "sea day" for every "port day," allowing for total relaxation and immersion in onboard enrichment programs.
