Thanks for the info, folks. I fully agree with the ban on personal irons onboard. Can't think of a scarier thing than a fire when you're hundreds of miles from shore. Everyone onboard is distracted enough to not need to put the ship at risk.
I'll do the rolling trick in addition to steam from shower and hair drier that should take much of the wrinkles out.
