4 days, round-trip Asia from Naha

About this cruise

This is the kind of trip that just works. 4 nights from Naha, visiting Ishigaki and Keelung, sailing July 31, 2026, and nothing about it feels forced. That gives you 2 days in port and 0 at sea, enough of each to find a rhythm. 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, Costa Serena: 3,014 guests, 13 decks. Entertainment, dining, and enough space that it never feels cramped. It's peak season, so the weather is at its best and the ship will be full. That's part of the fun. Hard to ask for much more than that, honestly.
