Your Director should be able to advise you, you're getting you diploma aren't you?
Be advised that you share your bunk bed with other cruise ship employee, put lots of longer hours, day & night, many activities to keep you going like the Energizer Bunny. Also you need to be a good swimming! Being able to work 6 months in a row, far far away from your friends & families, hardly get a vacation during the holidays. The tips from the cruisers are what you get for income. not bonus pay.
