If I don't but a premium parking ticket does that mean my only option is the free lot ? Are all the parking spots by the venue , now considered premium , or VIP guests , And handicapped ?

Free lot

Yes there unfortunately, Uber is great to use

Yes, you'll free park. You also have the option to see if they have availability I the VIP lot, but you'll pay cash for that. Good luck

Yes, a portion of the event ticket goes to the city of Mountain View for parking and the lots are in proximity of the venue
