Did they check up I-30? East of Mesquite is I-20; east of Garland is I-30. I would think there would be some rooms available, since it's the route to Arkansas and not Louisiana. There are a lot of motels along this route.
Nothing within 100 miles of Greenville. Kaufman, Terrell, Mesquite....nothing. I guess I'll start west of Ft. Worth.
Hotwire shows Roanoke (Fort Worth Areas) with at least one room for $141 a night, available Thursday - Monday.. (Four star, of course..)
