Here is the response from Tesla to my inquiry regarding how those attending the unveiling can reserve a Model 3:
You can reserve at the event itself, but if you'd like to secure an earlier reservation number then I'd recommend you visit one of our local LA Tesla stores on the morning of March 31st as they will start taking in-person reservations then.
If you are staying somewhere near the airport, then Santa Monica or Century City would be the closest stores.
Let me know if I can provide any more information.
