4. How long does it take to drive between San Francisco and LA?
I was on a job in Menlo Park, just a few miles outside San Francisco, and then we decided to make a trip down to Hollywood in the north part of LA to visit the Universal Studios theme park.
The ride down took about 6 hours, exluding a one hour stop in a small Danish village I don't recall th name of. This was on the 101. On the return trip we used I5 which saved us an hour making it 5. Well, we did drive a little bit faster than the allowed speed limit though.
I'll guess there would be another hour to reach central LA. And it also takes an hour due to traffic from where we lived to SF. Considered you might want to make some stops and that San Fransisco is not an easy town to drive in you may estimate about 10 hours for your trip.
If you take the Pacific Highway 1 then expact alot more hours, but it probably very nice. I5 is totally boring road in the middle of nowhere.
Most people recommend to take a flight since it's apparently whery cheep and doesn't take long.
However, if you don't plan too see any special in LA you could probably skip it. And about Hollywood and Beverly Hills it's not much to see actually, so if thats the reason for your stay then skip it. LA however have numerous theme parks which may be fun to visit, but it's not much to a city more like a gigant suburb.
Anyway California is alot like home but also totally different at the same time. If you are the visit a McDonalds take a crash course in Spanish first, it would help significantly. :-)
