Hello from a NooB!

I'm planning on a family roadtrip this summer from Vancouver to Los Angeles (and back). I see a lot of very valuable info from this community so !

I've got 15 days that are broken down as :

Travelling on the 101 =

Vancouver to Cannon Beach = Day 1

******need to make stops Until I reach San Francisco

SanFran = 2 days ..mmmm Napa :)

Get back on the 101 to LAX (non stop or should I break - if so where)

Time in LAX = 4days

Return = ~3 days..

Any suggestions on where to stop ? Places of interest etc..I like to do approx 6 hrs driving max as I want this to be a leisurely enjoyable drive.
