I have tickets to the race on June 20th at Infineon. It will be myself and my two kids (5 and 8). It's going to be the first race for all of us. I know traffic can be a bear & I'm debating driving up early that day (I live in San Jose) or get a hotel room for the night before. Realistically, how early should I plan on arriving at the track to avoid a lot of the traffic? Will there be stuff going on that could keep two kids fairly happy/occupied?
