Neecy: On the Triumph (Apr. 5th, Western Caribbean), there was a laundromat right down the hall from us on the Riviera Deck (lowest deck), but we never used it.
I had the ship's laundry wash and iron a new shirt I brought for Formal Night--$3.00 There was a special on laundry about mid-week. You could get all your laundry washed and folded--all that would fit into one laundry bag--for around $12.00. Next time I go, I will not bring as many clothes. Laundry and dry-cleaning service was quite efficient.
