KOA Campgrounds - Often excellent chain of privately owned campgrounds. Red Roof Inns - Very nice budget chain. Another quality leader. Super 8 - More expensive but still budget choice. Travelodge - Often not recommended.
Quality varies too much.
Excel Inns - Regional budget chain in Midwestern U.S. and Texas. Often very nice. Many properties are managed by on-site owners who often infuse some personality and regional characteristics into their motels. In all cases, ask for discounts. Many motels give discounts to AAA and CAA members.
