shower: 1$/3min. washing machine: 1,25$/load, dryer: 1$/20min. machines are old, dont wash properly and barely dry. I you can, wait for the next laundry. Also, even if there is a "full" sign at the entrance of campground, ask ranger, they usually have a cancelletion list then you can choose your site.
