I always bring a steamer, but I hardly ever have needed to use it. I think the last time I used it was about 3 cruises ago! I pack each of my outfits on a wire coat hanger that's then put into a plastic dry cleaner's bag before being laid out in the suitcase. It's amazing how wrinkle-free it keeps my clothes, and unpacking is a total breeze. Also, I bring along a spray bottle of Downey Wrinkle Release (but be careful-- put it in a zipper bag in case it leaks!), which I find works very well.
