We will have 1.5 days to spend on the coast in August. We can either drive to Astoria from our flight arrival in Portland early Saturday morning or drive to Florence from Eugene later in the week. We are a family or 4 with 2 older teens. Interested in local shops and culture, great views, maybe some walks on the beach. We can either stay put in one location, or drive up/down the coast to Newport before turning inland to I-5. Does this make sense with the time we have? Recommendations appreciated. Thanks!
