Hi Karen...I think you get the picture. NO irons allowed. It poses a huge fire hazard on board. Not that you'd do anything like forget to leave it plugged in and leave your cabin, but others might.
There are many good solutions to the age old wrinkle problem. Portable Steamers, wrinkle release products that you spray on, hanging your clothes in the bathroom during a shower, etc.
Most of my stuff is also cotton, and I've found very few wrinkles when unpacking on board. I also have all my cotton shirts laundered with light starch at our local dry cleaners, so this really reduces wrinkles from packing. My wife has no problem with wrinkled dresses, but most of them are not cotton.
I'd also suggest sending out anything really wrinkled to the ship's laundry. You can have a "press only" for only a few bucks and get it back the next day.
Good luck, Steve
