Hi- We will be driving down the coast from San Francisco and ending up at DL. We are going to take a few days to do that and are stopping in Cambria(Hearst Castle) on Sunday, July 9 ( we have tour reservations at Hearst Castle at 3PM). How feasable is it to wake up early on Monday morning and drive to Santa Barbara to make a 10:00 AM departure time for a whale sighting tour? How long will the drive take? Thanks for your input.
