It may be interest to any reader that the Royal Caribbean Cruise Line does not seem to have self service launderettes on their cruise ships.Laundry service provided by a ship "ain't cheap". As a "cheap skate" may I recommend taking along a bottle of Woolite and washing undergarments and socks in the bathroom sink. Usually, shower stalls will have a clothes line. Or you can buy two suction cups in a hardware store along with some twine and struing you own line in the shower or tub area.
The last time we had the ship do our launtry, the underwear came back starched.
