Thanks everyone! We definitely take advantage of the onboard laundry - as the PP said, it is very reasonable (better than at home!) and they do a great job. We do have a nice handheld steamer though that DH uses for his work clothes just when he needs to knock out a couple wrinkles between trips to the cleaners, so we thought we might bring it for a quick touch up for anything that gets crumpled in our bag. Great to know we can take it!
