Your Personal Steward onboard "Silver Cloud" will ensure that your clothes are perfect for you to wear at anytime onboard, their Laundry Service is second to none, & although sometimes it may cost a little extra, depending on your class of Suite onboard, it is really well worth it for it's benefits!
If you are lucky to have an "Onboard Spend" or "Ships Credit", then this can be used to good effect for this service, because you are going away for a Special Holiday, & should not worry about any work at all, while you are enjoying yourself onboard "Silver Cloud".
Its due to power restrictions on the cabeling, its not like a home electricity supply. However, most ships offer a laundry service and for example on P&O's Ocenana they have self service free laundries with washers, dryers, Irons and ironing boards.
Ensure the ship you book has a self-service launderette.QM2/QE2 and NCL ships have them.only one i have found not to is RCC.
My wifes favourite comment is the ironing on board, although on P&O the laundries on each deck are ideal even for the odd gentlemen presser.
If not as soon as we board we arrange for the cabin maid to sort and pay her or give her a gift, it works and in a timely way.
Some cruise lines do have self-service laundries, irons and ironing boards. There are usually long lines of crabby people waiting to use them.
Do not cruise to do laundry or ironing. Travel irons are a major no-no on cruise ships for safety reasons: It's far too easy for someone to use a bed as an ironing board, put on the freshly-pressed garment and sally forth for the evening's activities, forgetting to turn off the iron. This is a serious fire hazard. Leave the iron at home and let the ship's laundry do the pressing for you.
Pressing shouldn't really be necessary if you pack each garment on a hanger and enclose it in a dry cleaner's bag. You might want to pack a small steamer, but hanging whatever is wrinkled in the bathroom after a steamy shower should turn the trick.
All Silverseas ships have laundry rooms. They are available without cost. Although you may have to wait for a space at busy times it can be a great place to make friends.
