In 2023, Royal Caribbean operated a prominent duo of ships from the port of Southampton: Anthem of the Seas and Symphony of the Seas. Anthem of the Seas, a Quantum-class ship, was the primary year-round or long-season vessel, offering 7- to 14-night itineraries to the Norwegian Fjords, the Mediterranean, and the Canary Islands. Symphony of the Seas, one of the world's largest Oasis-class ships, also made a significant appearance in Southampton for the summer season, providing U.K. travelers with the unique "Central Park" and "Boardwalk" neighborhoods at sea. For those seeking shorter trips, Liberty of the Seas and Mariner of the Seas also offered limited "Weekend Getaway" or "Bruges & Hamburg" cruises of 2 to 5 nights. These ships made Southampton a premier gateway for European cruising, allowing passengers to avoid long flights to the Mediterranean while still experiencing the industry's most technologically advanced "Megaships."
