Since I don't have a washer and dryer, I get to go to the Sit-in-Spin quite often. What are you afraid of with the dryers? I've never had a problem, but the one I use always has an attendant on duty. I would use the "warm" setting (not hot) and put in the extra money for the longer drying time. You can also put in a few white or light colored towels for a couple of minutes to see if there is something funky in there that you didn't spot to begin with.
