Can't speak for that particular ship, but there have been laundry rooms on Main in the Carnival ships I've been on. It's three dollars to wash, three to dry, and one for detergent....and you need to bring quarters. You might be able to get some from the casino if you forget but I would not count on it. It's $15.00 for them to do it for you. Yes, they have the bag, and the steward takes it for you.
