Sorry for the delayed response on this, as it's mostly after skiing season now...
I had gone to the Loon resort in early winter. There were 2 or 3 charging spots in the general parking lot near the back. Unfortunately at that time, some of those spots were occupied by construction equipment. There was another Tesla that I saw there, besides for mine. Also, it was not a busy time, and I had stayed over night, so I could just plug in as long as I wanted over night.
