Thank you for your replies and help!

Yes we do like twisty roads, and want to do a road trip for 3 days. We want to stay North as we've already done in the past the SF to LA coast. The Yosemite Park, Sequoia trees, and Napa valley seems best. We haven't yet booked any hotels are chosen roads and itinerary.

We prefer comfortable b&b or charming hotels (with parking) but it's not easy to decide from internet sites, we do want to avoid big fancy hotels that all too often lack soul.

Any advice on itinerary and hotels would be great!
