I figure we do enough laundry at home, we can splurge to have the cruise line do it for us. Some lines also have self-serve laundry facilities on some of their ships, but I've never been tempted to use one of those, either. We've done at least a bag of laundry on each cruise and in all that time- one lost set of skivvies. (And as noted we don't put anything in the laundry that is super delicate.)
