Ok... so after making many many adjustments for folks my tour schedule is now locked down. I've submitted it to Tesla. FYI, they may have a few adjustments. As soon as they confirm that everything is good, I'll send out another email re-confirming tour slots. So be sure to check your email tonight before going to your tour tomorrow.
I did my best to place everyone that actually provided some scheduling preferences. But I'm sure some didn't get the time they wanted or I might have missed something in the hundred or so emails where someone wanted a schedule adjustment. For that I appologize in advance.
