I see that you are from Kirkland. Both lines offer a 28 day cruise from Seattle on September 28, 2025. The Princess cruise is on Discovery and terminates in Singapore so there are other ports besides Japan. Holland America has the Westerdam ending in Yokohama and is more Japan intensive. We prefer trans pacific cruises so there is only one long flight. We were on the Westerdam for the 2023 cruise and loved it. We took many private tours. We have the Discovery booked for 2025 just to do something different and we haven't visited Singapore in years.
