My husband has a conference in Lake Tahoe in mid-May. It starts on a Wednesday evening. Our thought was to fly into California the Friday before to see some of the other sites in the area. Initially we were thinking a couple days in San Francisco with maybe one night in Napa Valley (plus something else). My husband has always wanted to do the drive along Highway 1 along the coast from L.A. to San Francisco. We've also tossed around an interest in Yosemite. Obviously, we can't do it all. With that amount of time (mid/late Friday to late Wednesday needing to be in Lake Tahoe) do you have any recommendations on where to fly in and what to do? (Who knows when we'll be back.) Is it worth doing a one day-drive from San Francisco out to Monterey and Big Sur and then back to San Francisco? Or is it better to fly into L.A. and take a couple days driving all the way up to San Francisco and leave off Yosemite? Or it Yosemite more wothwhile than the drive? Just curious what other people's thoughts are--I can't decide!! Wish we had more time to do it all. Thanks in advance!
