We are planning a trip to the west coast at the end of July into August (2014). We wanted to fly into San Francisco, rent a car and drive seeing the sights along the coast and hitting Portland and ending in Seattle. Any suggestions for an itinerary? Not sure how many days we will need to do all that. Would likely have 7-10 days. We haven't booked airfare and our dates are somewhat flexible. We are a family of 5 (3 girls-12, 17 & 19). Is it better to travel up the coast on route 101 vs route. 5? Any suggestions would be appreciated.
