I think the primary goal of hotel/motel laundry with respect to towels is to get them white. Softness is probably way down the list.
I'd bet the towels hotels/motels buy are selected for durability/washability first, and everything else later, unless you're lucky enough to stay in a really 5-star kind of place. A Comfort Inn or Days Inn towel probably wouldn't be comfy-soft even if washed in our home equipment. People use those motel towels for everything from windshield cleaning to butt-floss to shoe-shining.
