If you still have time, the ferry ride from the ferry building at the end of market over to jack london square is a great ride right under your man-crush bridge. Great photo ops, and then you get to see all the massive oakland cranes up close (the inspiration for the At-Ats in Empire)...
Also remember to try out the San Mateo/92 bridge next time you are up -- set cruise control for 55 mph in the right hand lane and give yourself a 10 minute day dream...
