First off I do not care what others wear!
Secondly, I really don't care what the staff wears!
Thirdly A cruise is a vacation I paid for, not the cruise line or the other people on the ship and is a vacation in a normally hot environment and is hardly special!
Fourthly A dress code shows elitism as well "WE shall decide what YOU will wear! If you don't like it go camping!"
VOTE NO ON DRESS CODES!
