I didnt start CDing Eden until she was 15 months. She is 3 now and still sleeps in diapers. If I had to use a coin op laundry mat I would opt for prefolds too. I would also look into G diapers. I think G diapers were almost created for your circumstance
You could use your prefolds folded in 3rds with the G pants rather then the flushable liners. The G pants wash well in the sink and air dry in a few hours time. Then you'd only be washing prefolds. Another advantage of G diapers is that the cheaper Gerber prefolds work really well folded in 3rds in the G pants and they are easy to find.
