FWIW: Back in 2019, the SO and I took a trip from NJ down to Savannah, GA, Charleston, SC, and back. At that time SC's around those spots were all on I-95, many miles inland and a pain to get to.
In Savannah, all the public parking garages (and there are a lot of these, mostly underground) had Wall Connectors for Teslas at no charge, except for the parking. If one is staying in town and playing tourist for several days on foot, as we were, parking at these garages is very convenient and cheaper than what the hotels charge. The biggest hassle was having to go back underground and move the car to a non-charging spot so somebody else could get in.
In Charleston, we went on cost, not on whether there was a Destination Connector around. But, as it happened, we Scored. The hotel we stayed at was organized with a ground-floor garage, with the rooms arranged in several stories rectangularly above the outside edge of the garage; kind of like there was a courtyard down below. We asked if they had a Wall Connector and was told, "No". But then they said that there was the occasional 120 VAC outlet on the pillars down there and we could use any that we could find, free of charge.
We found an empty spot right next to a pillar and had the mobile connector up and running shortly. 5 miles of charge an hour isn't much, true, but if one is going to be parked for days those miles add up. We were full up before we left going northbound.
We did stay overnight in some $RANDOM place in North Carolina that had a Supercharger up the street and in Lewes, Delaware, likewise. But that's like saying one has been driving an ICE car and stopped in a town with a gas station.
And that's been generally the case with our driving all over the Eastern half of the U.S. over the past five years: SC may not have been that common when we started doing that, but there was always one handy when one needed to charge. And that is, perhaps, the point.
