There are 5 or six Teslas charging here at any given time while I have been here charging for an hour. It is not even on the map yet. Damn this one is gonna be really busy with possible wait times.
As with a lot of places, I would speculate that the early bird gets the Supercharger. I was there this morning a little before 9AM and I only saw two other cars charging in 30 minutes (only one at a time).
The physical layout of this site is confusing. I drove down the wrong aisle in the parking lot before figuring things out, and I can see a lot of people making that mistake. Also there's no obvious place to queue up, if it comes to that.
Still, 16 stalls is a lot compared to some other places.
