Each quiet pool has a laundry room. It's really nice to do my laundry while sitting at the pool as opposed to doing my laundry while cleaning the rest of my house. I've offered to go to WDW to do my laundry any time!
Keep in mind that the $2 to dry doesn't always get things dried. On cottons, etc. sometimes we had to go through two rounds to get everything dry instead of just to the damp stage.
