No self-service laundry on Celebrity ships. Go to Walmart and buy plastic clothes clips apx. $2 for 2 dozen. You can "rinse" out your delicates, socks, t-shirts, etc. with shampoo and hang them on the line in your shower. If you have a balcony, hang the shirts/swim wear on the back of your chairs so they will dry faster. You really don't need anymore clothes for the longer cruises. Swim suits and short outfits are the outfits for daytime. Co-ordinate your casual outfits for evening. Don't be afraid to wear something more than once or with different top or accessories, etc.
We are on the Constellation next month and will be bringing our oldest underwear, socks, etc., that we planned to toss anyway and will do so on this trip. It means we pack a lot but that leaves room for the inevitable stuff my wife will buy. (NG)
Only if you wash in the sink in your cabin and dry them on your balcony!
They do have an excellent ship laundry. It is a little expensive, but they do a good job pressing suits and formal dresses. My husband always sends out his dress shirts first thing.
I usually use the ship's service to clean and press my tux when I arrive. I have to do it quickly since the first day out is usually a formal night.
We just finished the majority of our packing and it looks like I'll have to sucumb to sending some items to be laundered as it just was too much trouble to pack enough underwear and socks for 18 days, even if I am throwing away some of the older items. It turned out that not enough fit that category.
