Multiple options for short day time stops, just got to think a bit beyond the norm. Big box store parking is hit and miss plus a lot of traffic but keep it in mind as a low priority option. Does the town have a sports arena, convention center or a Casino.? Fraternal organizations such as the VFW or Shriners. Church parking lots are another source. RV sales or car lots.
The trick is you need to plan ahead and start making phone calls. Maybe the city visitor, tourist, or parks & recreation office might be a good start.
Good luck.
