The Sun does not have self-serve laundry facilities, but they do offer laundry or just pressing for a fee. It wasn't that expensive. Also if you wait until the 2nd or 3rd last day you can fill a bag and get it all done for $20.00. Hope this helps.

I was on Norwegian Pearl on March 1st, 2008. There were free washing machines and dryers; you only had to bring your soap. There were irons and ironing boards. If I remember well, there was one laundrette on each three decks.
