A dozen lucky Model 3 reservation holders are getting an all expenses paid trip to the Gigafactory grand opening. Set for July 29, the grand opening party of Gigafactory 1 outside Reno, Nevada, will mark the first time the public has been invited to the sprawling and still-under-construction facility.

Electrek notes that twelve lucky reservation holders for the Tesla Model 3 have received invitations to the grand opening, with Tesla picking up the tab for airfare, transportation, and lodging:

Hello,

Congratulations! Through random selection, Tesla has chosen twelve Golden Ticket winners from all those that placed Model 3 Reservations on the opening date to receive an all-expenses paid trip to our Gigafactory Grand Opening event on July 29th, 2016 in Reno, Nevada. We are excited to share that your name was chosen in this drawing and that we'd like to invite you and a guest to join us at the event.

Round trip economy class airfare, transportation, and accommodations will be provided. Tickets are non-transferrable. For additional details and to redeem your package, please contact goldenticket@tesla.com.

We look forward to seeing you and your guest at the event!

Best regards, The Tesla Team

That the invitation has been extended to only first-day reservers limited the potential pool to... 150,000. So far more than 373,000 people have placed Model 3 reservations, holding their spot in line for a $1,000 fee. The Model 3 isn't expected to start production until late 2017, with the car's $35,000 starting price dependent on getting the Gigafactory producing battery cells in mass quantities.
