Thanks for all your help. Gosh, so New Zealanders are 'aliens' !
. I hope another 'alien' that has been on a recent cruise can post with their experience. I don't mind getting finger printed, or passport scanned, I just don't want that stamp!
What if we didn't get off the ship for the whole cruise? Surely we havn't left the USA if we don't visit any other countries? Of course we would love to see Cozumel or some of the other islands, but we could just stay in a deck chair on the boat!
