Princess's March 2025 release puts the Diamond Princess Singapore season in November 2026, and the end of the season depends on which source you read. The release says 11 sailings between November 2026 and March 2027. One trade report describes a shorter window.
Sources and facts checked: November 3, 2026 (America/New_York). Season dates, itineraries and terminals change. Check and verify with Princess for your sailing before you buy flights.
OTGG could not confirm the November start on a Princess booking page on October 29, 2026. The useful work now is checking your sailing with Princess.
The short answer
Princess's March 26, 2025 release says Diamond Princess will sail from Singapore on 11 voyages between November 2026 and March 2027, visiting 28 destinations in eight countries. Voyages run 10 to 31 days. The release gives no first sailing date, and a trade report describes a December-to-February season, so verify dates with Princess.
Diamond Princess Singapore: what Princess announced
Princess published its Southeast Asia program for 2026-27 in a release dated March 26, 2025. The release says that, on sale now, Diamond Princess will depart from the homeport of Singapore. It gives 11 sailings between November 2026 and March 2027, with durations of 10 to 31 days, and 28 destinations across eight countries.
The release names Singapore, Malaysia, Thailand, Vietnam, Japan, Taiwan and Hong Kong, though it does not list all eight countries, and it is the primary source for everything this article states about the season unless another outlet is named.
Where the dates disagree
Three details differ between sources. Princess's release says the season runs November 2026 to March 2027. TTG Asia reported on December 18, 2025 that Diamond Princess and Sapphire Princess would sail from Singapore in a twin season from December 2026 to February 2027, then both be based in Japan in 2027.
Cruise Industry News, in June 2025, gave durations of seven to 28 nights and a guest capacity of 2,600. Princess's release says 10 to 31 days and 2,670 guests. This article uses the release for all three. Check the dates for your sailing before you plan flights. Do it first.
Which sailing opens the season?
The release says the season both starts and ends with sailings between Singapore and Japan. It describes them as options of 14 to 31 days that pass through Taiwan and Vietnam. Which of the 11 voyages opens the season is not stated.
The release does not give a date for the first departure. Look at the sailing list on Princess's own site.
The late-night stays
Princess lists late-night stays in four places, namely Ha Long Bay/Hanoi, Hong Kong, Bangkok from Laem Chabang, and Kyoto from Osaka, per the release wording. A late-night stay means the ship is still in port after dark.
The release does not say how many hours each stay lasts. Check the itinerary for your sailing, because a late-night label is not a time.
The holiday-season sailing
For Christmas and New Year, the release describes a 14-day Malaysia, Thailand and Vietnam itinerary, with named ports at Port Kelang for Kuala Lumpur, Phu My for Ho Chi Minh City, and Laem Chabang for Bangkok.
That is the sailing to price first if your dates are fixed.
The long run to Japan
A 31-day Southeast Asia and Japan itinerary adds Ishigaki, Okinawa and Kochi, plus Kobe for Kyoto. It is the longest voyage the release names.
If one long-haul flight is the biggest cost of your trip, a longer itinerary spreads it over more days. That is arithmetic, not a Princess claim. Price both before you choose a length.
Who else sails from Singapore?
Cruise Industry News and CruiseMapper, both reporting in June 2025, said Sapphire Princess would also sail from Singapore in 2026-27. They called it the first time both ships sail from Singapore together since 2018-19. Cruise Industry News gave Sapphire Princess 18 voyages.
Those figures come from trade reports, not from the Princess release. If they are right, Singapore sees two Princess ships that winter.
The ship herself
Princess says Diamond Princess carries 2,670 guests. Regional touches in the release include Kai Sushi, Japanese-inspired cocktails from mixologist Rob Floyd, and the Izumi bath.
The release also lists the standard Princess venues: Sabatini's Italian Trattoria, the Lotus Spa, Movies Under the Stars and the Princess Theater.
Where does she dock in Singapore?
The Princess release does not name a Singapore terminal. TTG Asia reported that Diamond Princess began her previous Singapore season on December 7, 2025, at the Marina Bay cruise terminal.
That was last season, not this one. Confirm the terminal for your sailing in your booking documents.
What to skip: unconfirmed switchovers
Skip any report of a one-off Singapore visit by another Princess ship unless Princess itself confirms it on its booking pages. This article found no Princess page that does, so it says nothing more about it.
Also skip planning around a fixed end-of-season month. The sources above disagree by a month.
Devil's advocate: book later
A careful reader will point out that a season this close leaves little time to compare, and that the dates still disagree between sources. Waiting for them to settle is reasonable.
The counter is that your own dates may not wait. A fixed holiday or a flight you have already bought narrows the choice fast. Open the booking page, pick a sailing and read what is available that day.
The OTGG bottom line
Princess announced Diamond Princess in Singapore in a March 2025 release: 11 sailings, 28 destinations, November 2026 to March 2027. OTGG has not confirmed the start on a Princess booking page. The first sailing date and the exact end of the season are the open points. Pick the voyage length first, then confirm dates on Princess's site.
