I did laundry at the CR during the last week of May. I used the machines in the South Garden Wing during the early afternoon. Each machine is $2 (so $4 per load). There were 6 washers and 6 dryers. I split my blues (mainly denim shorts) into two dryer loads from one washer load. The dryers worked fine that way. I brought my own Wisk tablets and dryer sheets. There is a sink with liquid hand soap which I used on a chocolate ice cream stain on one shirt (forgot my stain stick).
I put the clothes in the wash and sat by the pool having a cool drink in the shade of an umbrella (my DH and 2 DDs rode the small water boats) and then 30 minutes later moved the clothes to the dryers - went back to my shade and then 30 minutes later folded all the clothes. Very easy and only saw one other person who was about 30 minutes ahead of me in the process.
Hope this helps.
