It will depend on when you want to do it. When I was there in August, I did the laundry twice. The first week, I did it at night. Getting a washer wasn't a problem but getting a dryer certainly was. The drying cycle is 40 min. But the dryers do not work that well at all. It takes at least 2 cycles to dry your clothes. It was cut throat trying to get a dryer. People can be ruthless even in a laundry room LOL! There was one woman who took over the laundry room. At one time she had 4 out the 6 dryers. Apparently, no one else was entitled to a dryer until she was finished. She literally stood in front of the dryers for the whole time. As soon as one became available, she'd jump right in and take half the clothes from one of "her" other dryers and put them into "her" new one. This created a huge back log for the dryers. That night, I didn't finish the laundry until 2:00 am.
The second week, I did the laundry in the morning while my wife took the kids to the pool. I had the place to myself.
I believe there is one laundry room in each building (6 washers and 6 dryers in my building).
