I'll be traveling to SF on Aug 9th for an interview and will have some time to explore the city.

I'll arrive at noon on the ninth and have the whole day to myself plus the afternoon of the 10th 'til about 8pm.

I have rented a car since I don't want to waste money on cabs going to/from the hotel to the interview site.

So, having never been there, I think I've narrowed down my choices for what to see/explore:

- Golden Gate South rec area
- Haight & Ashbury St's
- Lombard St
- Maybe squeeze a visit to Alcatraz
- A ride on the Powell-Hyde tram

I also considered going to Fisherman's Wharf, but I hear it's waaay to touristy.

So I want to know the following:
1) How do I get to the GG rec area? Do I have to go all the way to the toll and exit right before it?
2) To go around Haight & Ashbury St where would be a good place to park and where else should I walk around that area?
3) Where do I get on and how much is the cost of the ride on the Powell-Hyde tram?
4) Can you please suggest any other attractions I could visit that are not too expensive? I'll be staying in Oakland and since I'll have a car I'm open to visit that part of the Bay Area as well.

Thanks!
