I am curious what you decided to do.
I was ready to book Seattle to Vancouver b2b with Vancouver to Honolulu (basically the opposite of you) in the fall of 2023. I call RCI and two employees have told me that it is not a problem. But everything that I am reading is saying that it IS a problem.
We just did a Florida to LA cruise, but it had a stopover in Cartegena (a foreign distant port) which apparently satisfies that law.
