From the second they take your photo, I think you are profiled by the cruise line in a database and they know a lot about you, your cruise history, your preferences etc. NOT in a bad way but from a customer relations standpoint.  I say that because on a recent cruise a staff member greeted me as "Miss Deborah" a name I never go by - I've been Debbie my entire life.  I am really a Mrs. but when my son and I first started cruising Princess, they linked us as Mr. & Mrs.  By our third cruise, they knew we were not married and "mail" etc was addressed to us individually.  What say you?
