Celadon Horizon – Incheon, Jeju & Busan

About this cruise

If you want the classic cruise without a massive time commitment, this is a strong option. 6 nights from Shanghai on October 1, 2026, visiting Incheon, Jeju Island and Busan. There's a stretch of back-to-back port days, so those days are busy, but the sea days around them give you time to recharge. Karaoke bars, hot springs, and temples draped in moss. East Asia does culture and chaos in equal measure. Most ports give you about 9 hours, so you can do more than just tick off the main sights. As for the ship itself, You won't go hungry on Spectrum Of The Seas. 6 restaurants come with the fare, plus 7 more when you feel like treating yourself. Being shoulder season helps: golden light, comfortable weather, and shorter queues at the popular spots. 6 nights of not thinking about anything except where to eat next. That's the pitch.
