but you may want to consider couchsurfing for 2 nights up in San Fran.
Some ideas for SF:
* Drive to the top of twin peaks - alternatively walk from 24th St BART to the Bernal Heights hill (as you'll need a friend in a car for twin peaks, but Bernal is easier to get to, not as high, but still a good view)
* Visit SF's China Town, not as authentic's as singapore, but still pretty hopping.
* If there's anybody you're meeting for lunch in downtown SF, suggest South Park where lots of geeks go
* Head to a farmers market on Saturday mornings at the Ferry Building
* Stroll down Valencia Street btwn 16th & 24th St and poke your head into random shops, like Paxton's Gate on Valencia, btwn 19th & 20th.
* Grab a burrito at El Farilto on Mission & 24th, the most fun is after a night of drinking around 16th & Valencia
* Walk around Fishermans Warf - it's uber touristy, but with checking out and smelling some fresh Boudin Bread
* walk down Haight St, and cross Ashbury St where the whole drug/hippie scene started in the 1960s - they used to give out LSD for free on that corner!
* Check out the golden gate bridge, maybe rent a bike and ride around the east and north coasts of the city, to the bridge.
* Visit dogpatchlabs - an awesome co-working space, let me know if you need an intro.
* SHDH
* And here's a bunch of free hip events listed on a calendar: http://sf.funcheap.com/
And lastly, visit some startups - if you send me a list of some companies you'd be interested in, I'll see who I know and suggest some others (like i/o ventures). And let me know your dates and I'll check out events as well
