The best time would be early morning

After 10 pm is good, too--the laundry rooms are deserted then, except on the last couple of nights. I'm a night-owl...family isn't. After they went to bed, I'd head out, put a load in the washer and head down to the internet cafe for a bit. I'd come back to switch to the dryer, wander off to see what was on the late-night snack table, head up to deck 9 for a bit (where it felt as if I was the only person on the ship) to just enjoy the night air and then come back for the clothes.
The dryers are just awful, by the way, so the tip about putting in enough quarters for an extra run is a great one. If you're in a hurry, pay the extra 1.00 and split your loads into two dryers. One nice person gave me this tip when she picked up her clothes. She had some time left on her two dryers which she pointed out to me so I could use them.
