Seas are generally very calm going down the coast and from port to port. The sail back up north generally is a little more exciting, but certainly tame by most standards. I live in No. Calif. near Sacto. and have sailed out of all three embarking ports you mention. I generally drive to the port regardless ( I am not a good air traveler). I must say the short drive to S.F. certainly beats the all day to San Diego. I am driving to LA in three days for my cruise departing on Sunday (no big deal). Nothing beats sailing under the Golden Gate though! Also when you return only being a couple hours from home and no crazy airports! Good luck whatever you decide, you really can't go wrong.
