Go to Santa Cruz for a day. Great Beach. A nice wood roller coaster on the boardwalk and some other rides for the kids.

Really you can walk around anywhere in San Fran and have a great time. ghirardelli square is cool (and they will give you chocolate samples in the store there), the Japanese garden/tea house is nice.

DO NOT GO TO 3COM park on a non-game day. I've traveled all over the world and been in some bad places, but that is the only time I have ever felt not safe. Drive by racial slurs and what not. Some body asked me what the hell I was doing there. I said trying to get out. His response, "I'll tell you the safest way to get out... not the quickest, but the safest." I had to cut past a school that was fenced in with 15 foot fence and the whole cement playground (ie basketball court) was covered in broken glass. It wasn't nice. But that was 7 years ago, it may be a little better now.
