Neptune's Silk Route – Busan & Jeju

About this cruise

If you don't need a long holiday but still want to get out on the water, this is a solid pick. 5 nights from Shanghai on June 28, 2026, visiting Busan and Jeju Island. The shape of this trip works well: open water on either side with 2 port calls clustered in the middle. Bullet trains visible from the harbour, cherry blossoms, and thousands of years of history. East Asia is a lot to take in. Of the stops, Busan tends to be the one people talk about: Temples on the mountain, fish markets by the sea. Around 11 hours per port on average, which is generous enough to go beyond the obvious. Spectrum Of The Seas takes the food seriously, with 13 restaurants to choose from. 6 are included, and the rest are worth the splurge. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. The timing works well too: warm evenings on deck, late sunsets, and a lively atmosphere. Sometimes the best trips are the ones you just go ahead and book.
