Is there a good place to spend the night with a good view of the ocean, especially where you can view big waves from your room?

In Spanish Head in Lincoln City is built down the cliffside right on the beach you can actually go down the elevator and get off and walk onto the sand

Yes. all along the coast. Google map the towns like bandon , Coos bay, mostly the towns south of Coos bay.

Sorry but no. I am not sure but there might be some vacation rentals between Charleston & sunset bay, most of them are individual homes though. Back in the late 1930's or 40's there used to be a hotel out at sunset bay. A typhoon ruined it though.

Gold Beach further south and Yachats and Lincoln City up north.

There is not. Florence. Newport. Port Orford. Bandon. These all have ocean views. Coos Bay is all bay views. Still pretty. Just a different water.

Not nearby. The Mill casino has a beautiful view of the bay though.

I don't think there is.....the nearest is a RV resort if I remember correctly and that's still a little over 2 miles away.
