Haven't used the Ohio rest stops but we travel by the clock and not the mileage. We hit the road no later than 10 AM (usually 9:15) and start looking for a place to park around 2 PM and pull over for the night no later than 4 PM.
We use to get up early and drive till almost dark but the next day was not fun. We really like our new arrangements but everyone is different so try it and see what you think.
