Swift Retreat – Jeju Island from Shanghai

About this cruise

4 nights from Shanghai, visiting Jeju Island. It sails March 13, 2026 and it's the sort of trip where you come back saying "I needed that." More sea than shore on this one, with 2 days on the water between stops. Bullet trains visible from the harbour, cherry blossoms, and thousands of years of history. East Asia is a lot to take in. Don't rush through Jeju Island, which is known as Korea's volcanic island of myth and beauty. From casual buffets to proper sit-down restaurants, Spectrum Of The Seas has 13 dining spots on board, most of them included. Timing-wise, spring usually means comfortable temperatures and lower prices than peak season. All told, 1 ports across 4 nights covers a lot.
