There are some nice ocean views in Bandon, Oregon. We rented a room from a place off the 101 called the Harbor view. It's since changed it's name, but the sign still says somehting like "formerly the harbor view" so its' easy to find.
When we were looking for a place to live I looked all along the coast and talked to freinds who live in other parts of Oregon.. I think Yachats is a nice little town, north of Florence. The drive is pretty and the sea lion caves are nearby. I didnt' think much of the motel we were in, just some highway no name.
Up a bit further is Waldport and newport, one of them has a pretty bridge, I dont remember which but they're very close to each other. Up north Talimook has lots of cows and green wet hills. it's really pretty.
Finally, Astoria has a neat tower about the oregon migration and a super neat bridge into Washingtons state. There are several visiters centers along the highway, be sure to stop in and get advice. I also found the AAA book on Oregon and Washington state useful.
We currently live in Coos Bay, Oregon. I hope you have a nice trip.
