We are planning a 15 to 20 day road trip up the Pacific Coast Highway starting in LA and going North to around San Francisco and the wine country then diverting to Lake Tahoe and Yosemite National Park. Most likely it will be in May or early June. Being retired, I can and want to avoid the vacationing crowds.

I would like to collect a list all the interesting sites and places to stay up the Pacific Coast Highway and see if you have any suggestions that would make me want to divert further inland. Some questions to start:

1. Is my selection of May to early June a good time to do this trip? I want to make sure I have the best time chosen for Yosemite.

2. Is there any compelling reason to extend my trip further North than San Francisco within my time constraints?
