Make sure Camp Carnival knows (if she attends), as well as the social director.
My son celebrated his 13th on the Fantasy and was nicknamed "birthday boy"by the social director. She mentioned him at almost every game and some fellow passengers even named one of the horses in the horserace "birthday boy" much to his delight.
