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.
15 wonderful cruises under my belt!
Next up: Carnival Pride 09/11
i have yet to use one. i hang the good dress clothes in the garment bag while traveling. If you unpack right away and hang up your clothes most of the wrinkles will fall out. IF that doesn't work, i will use the iron in the self-service laundry room. The steamy shower works well also.
