4 days, round-trip Asia from Naha

About this cruise

Some of the best trips are the ones you barely had to plan. 4 nights from Naha on July 16, 2026, visiting Ishigaki and Keelung, and you're home before the laundry piles up. The mix of 2 days ashore and 0 at sea means you won't feel like you need a holiday from your holiday. Street food that'll ruin you for takeaway back home, ancient shrines, and cities that run like clockwork. People come back from this cruise talking about Keelung: Taiwan's rainy harbour of night-market magic. Roughly 8 hours ashore per stop. No need to rush. Costa Serena carries up to 3,014 guests over 13 decks. Multiple pools, a theatre, and more restaurants than you'll get through. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. And July means long, warm days. Good for the ports, good for the pool. 2 ports, 2 countries, one suitcase. That's the appeal.
