I have driven that stretch of road several times the areea is beautiful. there are places to camp all up and down hwy 98. I stayed farther east due to family but I don't think you could go wrong staying there. If I had a month off I would try alot of the places along that area. Those barrier islands along that area are to die for. The waters great and I am sure you would enjoy it. As far as specific amenities I cannot say .
