Lisa, I took a small travel iron and a steamer with me on my recent cruise on The Mariner.Of course I was very careful with these ,and made sure not only were they unplugged but cooled as well befour I put them up.
I used the glass top coffee table with a towel folded over it as my ironing surface.It was very helpful to freshen my clothes that always have some wrinkles no matter how careful I am when packing.
If you decide to do as I did ,please remember all safety precautions because you not only have your life in your hands but literaly thousands of others!!!!!!
Oh, and as my sainted mother always said,there is no such thing as a dumb question! Have a great time on your vacation! I sure did!!!!!
