On the Huntsville TX supercharger, as I recall, coming to it from the north was a pain to get to. we had to use a back road to get there since the frontage road was one way- There are many Superchargers at Hotels and all of them that I can recall have the 30 or 60 min general parking signs on some of the chargers. Also, the one in Casa Grande AZ which is very popular for Tucson to Phoenix travelers has several of the spots as general parking, and it's frequently blocked, or was the last time we used it. Luckily, we've never had to wait for a charge there, but we have gotten the last stall a couple of times. I think in the case of Casa Grande, generally it's a lack of other parking not just people being rude. But I'm sure there is some of that too.
