The great Southeast Asia sweep: start under Hong Kong's skyline, work down the Vietnamese coast, add Bangkok and end in Singapore. Ten to fourteen nights of the most varied port days in cruising.
The route at a glance
One-way from Hong Kong to Singapore, November to March. Celebrity's Solstice sails twelve nights in January 2027: Hanoi via Halong Bay, Hue and Danang via Chan May, Ho Chi Minh City via Phu My, Bangkok via Laem Chabang, Ko Samui, then Singapore. Holland America's Westerdam runs a fourteen-night December 2026 version with an overnight in Halong Bay. Four sea days is typical, and several ports sit an hour or two from their headline cities - Phu My to Saigon is 90 minutes each way, so ship excursions earn their keep there. A shorter regional alternative lives in our library at Southeast Asia, Singapore to Bangkok, 12 days.
Who this route suits
Best for culturally curious travelers who want Vietnam in depth without a land tour, food lovers, and anyone pairing the cruise with extra nights in Hong Kong or Singapore - both are worth two days on their own. Less ideal if long transfers from industrial ports frustrate you, or in shoulder months when heat and humidity peak; December to February is the comfortable window.
What it costs
Celebrity Solstice's January 2027 sailing lists inside cabins from $2,393 per person including taxes ($200 a night), with tracked prices averaging $1,855 over time - watching fares pays off on this route. Open-jaw flights into Hong Kong and home from Singapore add roughly $100-300 over a roundtrip to one city. Onshore costs are low once you are off the ship: excellent meals run $5-15 in Vietnam.
