All the washers and dryers are credit card operated, you will also need your magic band to open the laundry room door at all times. There is 5 washers and 6 dryers in every comfort station. If you are staying in a preferred loop (100,200 or 300) there is one comfort station for the 100 and 200 loop while the 300 loop has its own comfort station. For full hook up sites (1600,1700,1800 and 1900) there is a CS 3/4 way around the 1600 loop that is shared with the 1500 loop also one at the entrance to the 1600 loop that is shared with 1800 and 1700. The third CS is in the 1900 loop and is shared with the 1700 loop. For the 2100 loop they share a CS with the 1100 loop. From my experience the busiest days to wash are Wednesday and Thursday as that is the middle of someones 7 day stay if they arrive on the weekend. Least busiest days are Sunday and Monday. Hope this helps and have fun.
