I know this is odd but maybe someone can help. On a cruise around the Hawaiian Islands (NCLs Pride of Aloha) will it be considered duty free and sell booze, etc accordingly when not in a port? I presume there won't be customs (although some folks aren't Americans) but will they have immigration even though we all leave from and return to an American port? I know I come up with the darndest things but since we will be staying in Hawaii for awhile after our cruise just wondered if I can purchase my booze duty free if possible!!! Appreciate some input here.Happy cruisin'!
