I don't know, Ron. In the "good old days," when I used to go to laundromats, I remember seeing frequent fights over the biggest washers, and even more fights over the limited number of dryers. The meek may inherit the Earth, but they do not inherit the laundromat.
Six loads may take no longer than one load, but six separate regular size machines take a lot more quarters than one super size front loader laundry machine. They're so big I sometimes wash my car in them!
