My advice is to stay very flexible, watch the weather, watch the radar. It may turn out that one part of the state has better odds of clear skies than another, which will be a lot more important than course quality.
When the 2017 eclipse cut across South Carolina, Stoney Hill was only 3 miles from the centerline. Skies were partly cloudy, and cleared in time for the show. The path also cut through Charleston, which was overcast all day, and people who planned their eclipse vacation there, lost out.
That eclipse also caused traffic jams. This year's may not be as bad, with the path cutting through more populated areas, but keep in mind that you may not be able to dash from one spot to another.
My plans to head to Texas for this year's eclipse are pretty shaky, but they involve aiming for less-populated areas (for traffic), and having a wide target area up until the last day or so, to maximize my odds.
(And don't do like the disc golfer who was driving from NC to visit us, but got freaked out by the traffic and decided to stop on the roadside and settle for near-totality. Trust me. A 99% eclipse is only 0.000001% as cool as a total eclipse.)
