@hawaiiboy you are moving up and down the 101 a lot - for such a short time .. why not bypass the tourist trap of Sausalito - where you can't park - and Muir Woods is lovely - but - again - time ... and I THINK you might even need to book time to even visit ....
ALT - From Santa Rosa - head out west go follow the Russian River and admire THOSE Redwoods. Seriously the 101 down into SF is never great.
