25 days, one-way from Tokyo to Sydney

About this cruise

The kind of trip where you lose track of what day it is, and nobody cares. 25 nights from Tokyo on October 18, 2026, visiting Keelung, Hong Kong and Subic Bay Freeport, with additional stops along the Southeast Asia. You finish in Sydney. The first couple of days are at sea, which gives you time to settle in and get to know the ship before the ports begin. The Southeast Asia route takes in Taiwan, Hong Kong, Philippines, Indonesia and Australia, 5 countries, and the differences show up in the food, the architecture, and the mood. Most ports give you about 10 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. By night three you start recognising faces; by night ten you're swapping numbers. That's the magic of a longer sailing. If you like having options (restaurants, bars, activities, entertainment), a big ship delivers that. Being shoulder season helps: golden light, comfortable weather, and shorter queues at the popular spots. You'll probably start planning the next one before this one's even over.
