What do you mean by "Valet only"? Supercharger should be accessible 24/7.Charging at 313 mi/hr. Note at least in the evening here on Friday area blocked off as Valet only. Security swung by and made sure we were charging and good to go. BTW Octane validates and the Flat White is excellent.
... if someone could figure out the exact parking rates (e.g. free for first XX minutes, then $X per hour), we can add that info to the Plugshare listing.

... Was told the lot is attended 24/7 and if they don't notice a Tesla exiting then call the number on the gate pedestal ... The "main" gate and exit are on the west.
