Princeton may have been able to understand the question(s) you asked, I couldn't really follow.
No you don't need to show a passport or other documents, other than a government issued ID when boarding an airplane to fly between U.S. cities.
If you are saying you are on the Westerdam leaving Seattle on October 24, 58 days to Sydney, with 2 stops in HI, I don't know what travel documents HAL will require for you to board. I don't know if HAL requires VISA documents on a cruise leaving the U.S. or traveling in the U.S.
I'd ask them or ask in the HAL Forums.
