We should point out that we only did this in the early hours of the morning. We were up because of the whole jet-lag thing and there is only so much jumping on the bed you can do before needing to get out.
Yes we did visit Alcatraz, Pier 39, Union Square, Sausalito, The Golden Gate Bridge etc. However Harry liked going up and down in lifts the most so we went from Hotel to Hotel trying to find the best ones :)
To those people Harry met in the pool at the top of the hotel - "you see it was me".
