We are a 50-something couple planning a first time trip to California, most likely late June. Plan to fly into LAX, and drive up to San Francisco, and down to San Diego. Total trip time is 12-14 days. We like a blend of sightseeing, beach-lounging, dining out, etc. we are thinking maybe 2-3 nights each in LA, SF & SD, with appropriate stopovers on long-legs. Your thoughts most welcome on:
1. Whilst in SF, is it worth driving to Yosemite?
2. Best places to stopover between LA & SF?
3. Best sights to visit in each of LA, SF & SD?
4. Is June a good time for sunny, warm weather but not too overcrowded?
I know that's a lot to ask, but I am at the initial scoping stage. Thanks for any help.
