A couple of weeks ago, I signed up for the Let us bring All-Wheel Drive Dual Motor Model S to you event that will be in Boulder, CO from May 25th - June 1st. It says on the event page that "Appointments will be confirmed by a Tesla representative from our California headquarters" but I haven't heard a word since signing up. A friend signed up as well but hasn't heard anything back either. Does anyone know how far in advance they confirm appointments? Another friend will be in town for Memorial Day and the three of us all planned on a test drive. I'll need to take him to the airport in the afternoon so it would be nice to have a confirmed appointment.
