I found some stats online and it normally fills up the day before as people generally like to be at their destination by the 4th. But you may be lucky. You could just Uber if that is viable. Or bart maybe. Either will get you there pretty quickly.
Maybe, not early,and Christmas and Thanksgiving are the worst!!!
Yes it would be.
This question goes out to The General Public, but I would imagine all of the parking lots will be full on the 4th of July.
