I don’t know about parking after 730.
I heard there is a new parking lot to ease parking but, also have a friend who didn’t display the receipt correctly or pay for it correctly and got a very expensive ticket.
Where are you going to be in the city?
If you are around Union Square, I would drive over and park at the Sutter Street Garage.
If you are going to be in the financial district, I would park at the structure just north of the Embarcadero towers.
seem cheap enough to me.
I am not familiar with the city. I am going to Pi Day at the Exploritorium; Pier 15. The child I am taking likes to ride the ferry. I am not adverse to driving, however.
