I will be on a cruise that is round trip from Oahu. This trip goes out of the US to Kirabati and then visits some more ports in Hawaii. I intend to spend a week in Oahu prior to the cruise and would like to disembark in Kona 1 day prior to the scheduled finish of the cruise in Oahu, so I could spend another week on the big island.
The cruise line told me I cannot do this and that it would be illegal. It does not make sense to me. I hope someone can advise me how to proceede.
