@daniel - if you already have travel plans, I'm absolutely positive that Tesla will work with you. I honestly would not worry about this.
Yeah, I make my travel plans 6 months to a year in advance, sometimes much longer for places that book up early. I'm not actually worried, I was just wondering how it works, especially with some people reporting that they have a hard time communicating with Tesla. With half a million reservations, communication has to be a nightmare. And I was wondering if I would even be able to get hold of someone to talk to about it before I place my order. I'm happy to postpone my order so that delivery happens when I'm home, but for that I need to be able to talk to someone before I've put the order into their system.
You will be fine. The only one I would watch out for is the 6 week trip.
Even then, let them know the blackout dates. They should be able to shift things around a bit.
My delivery estimator page says Dec 2017 to Feb 2018, and the six-week trip doesn't happen until July. But I'll be gone for 3 weeks in January/February.
@bonnie: I believe you got your invite. Does the invite include a contact person, or do you only get a contact person after you place your order on line?
