D.S.
So many places....I stayed at this cheap motel on the oregon coast. The Nordic I believe it was called. It had a pool and was right on the beach with all rooms having a view. The oregon coast is great. It was about $100 per night. Anywhere on either the Oregon or Washington coast.
Vashon Island is great too. There isn't a lot in southern Washington. Portland is nice. McMenamins in Troutdale or any of their hotels are real unique.
