There is no selfservice launderette - you send your clothes out and they are returned the next day. Prices are reasonable and are on the RCI websit.
There are no laundrettes that are available to passengers on board however you can get your laundry dry cleaned or laundered and if you wish just pressed with an ultra quick or next day service. The prices are not bad and occasionally you should get a special offer to fill a bag for $15 or $20. Hope that Helps ... Nei.
