Well, I know the "official rule" is NO irons, including steamers in the staterooms. The normal response you usually get on this subject from most is, a strong NO, and the reasons are: "you will surely burn the ship to the ground if you use one, and you will forget to shut it off, and think of all the people whose lives you put at risk JUST to iron your clothes in the room. " OFFICIALLY no irons or any HEAT type of device for safety reasons.
