Asking what is unique about a Motel 6 is a contradiction in terms. It was a Motel 6. We stay there when we are transporting our cats. Some versions of Motel 6 are better than others: our stay in a Tuscaloosa, AL version was at the top of our experiences this time. A stay in Texas was middlin' good.
Our stay at the Mojave, CA Motel 6 on State Road 58 was okay. We arrived late, having made reservations the day before. We, and our cats, and all their equipment, were placed in a second floor room, which required lots of hauling. Because we had animals, the room we were assigned was in "needy" shape. Though basically clean, the bed linens were worn, with cigarette butt holes. The toilet looked like it hadn't been scrubbed under the rim for some time, and the corners of the floor had collected crumbs of this and that over time. It was more "bare bones" than many. Everything worked, though.
