do you ABSOLUTELY have to drive? cousins that use to live in SF, kept stressing how expensive parking was. We were there in Oct2006 and VERY easily got around. The Bart system is great, although needed some help to figure out how to pay for where i wanted to go. http://www.bart.gov/index.asp Buy a Muni Pass that's good for all the cable cars and buses. One way cable car ride is already $5. We bought a seven day pass even though we only needed it for 4 days, then sold it to some other tourist so they could use the remaining 3 days. It was fairly easy to get around, although a bit chaotic at some stops (esp chinatown) since you're litterally packed in like sardines. people enter from the front, back, etc. so packed never really see the bus drivers checking for fares, etc.
