My vote is for anywhere between Hearst Castle and Monterey...that wonderful Highway 1 is a true pleasure, and at that time of year, the vistas of the ocean are incredible.

I live just south of Los Angeles....would probably drive 4.5 hours up to Hearst Castle (city of Cambria, any hotel on Moonstone Beach Drive is worth it) and stay there on Friday night, then meet you all anywhere along the coast up north on Saturday. Would probably end up staying at Ragged Point Resort on Saturday night (on an ocean cliff), and make the entire drive back on Sunday.

I did the drive a couple of weeks ago (the return trip was all the way back home from San Francisco...in 6 hours doing a straight shot on the inland 101 highway) and in the xfire it was far more pleasureable than my old miata...was surprised how easy the long trip was.
