LAH-The dryers take a LONG time to actually get your clothes dry. We had to wash jeans and it took 3 cycles to get them dry.
I brought my own detergent. Put it in a margarine tub, put a rubber band around it, then put it in a ziploc bag in my suitcase.
I used the laundry room by building 17/18. I went down at about 8 in the morning. It was very peaceful, just me and the birds. I sat out by the pool and watched the mist rise. Enjoy the peace of the moment! Have a great trip.
