I just recently went here and i think that it was a blast. my favorite part was riding on the trolleys if and when you go there i definately recommend that you buy a three day pass for the trolley because it lets you on the buses and the trolley for free for three days. i also think that when you visit there you should go the Ghiradeli factory and try some chocolate. it is delicous and dont forget to check out Alcatraz Island. that was amazing you are able to walk into some of the cells and hear some of the stories from the inmates. A must when going to San Francisco.
