Nancy, all Carnival ships have self-service laundry areas with coin operated washer & dryers as well as irons & boards. You also can give items to be ironed to your steward.
Another alternative I've used myself is to hang clothes in the bathroom while I take a hot shower ~ that can take care of a good many wrinkles!
Hope that helps,
A tip you may want to try, I did this last cruise and it really worked. Put all the nice stuff (dresses, mens suits) in the plastic bags that you get from the cleaners.
I don't know how or why, but nothing gets wrinkled in those. Good luck and give it a try and hopefully you won't need to iron anything.
