I'm new to this website and so far I like what I see. We're planning a 12 day family vacation to California flying into San Francisco and flying out of San Diego. The plan so far is to spend 3 days in San Fran, rent a car and drive down the coast (Hwy 1) seeing Hearst Castle, Big Sur and Pebble Beach. We have two nights booked at LA Live Hotel in L.A. then the night before we leave is spent in San Diego. I'd like to get some advice on what to see/ what to avoid/ where to stay / and should we take the interstate at some point after driving down Hwy 1. I've been told not to bother taking Hwy 1 all the way to L.A. (if that's possible).
Any help / suggestions would be greatly appreciated.
P.S. Our two boys are 15 and 22 so we weren't planning on going to any zoos or anything of that nature.
Thanks for any input.
