Just make sure you read the instructions on how to pay for your parking, or you’ll find a very nice ticket on your car when you return (if it isn’t also impounded.)
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.
Take the cannoli.
