My husband, 4 year old daughter and I will be traveling to the Oregon Coast the last week of August. We are interested in seeing marine wildlife and scenery and of course, keeping a 4 year old entertained. We plan to fly in to Portland (from Grand Rapids, MI or Chicago). I would love some advice on where to stay, what we absolutely shouldn't miss, etc. We have discussed driving to Newport (from Portland) and then traveling back up the coast before departing again from Portland. We have nine days. If possible, we would love to see the Columbia River as well. Any suggestions would be greatly appreciated.
