Advice on driving Oregon's coast road?

We hope to be in that line of southbound RVs on 101 down the Oregon coast this summer too. We're planning on picking up 101 at Astoria and going to Reedsport before heading east to Collier Memorial State Park. I was planning on 3 days to make the approximately 200 mile trip and staying somewhere in Astoria then a stop about half way & a night near Reedsport.

Any advice on places to stay or must stops? We'll have a toad.
