Speaking for Portland Oregon, you will find all kinds of cuisine. Turkish, Indian, Ethiopian, Lebanese, Japanese and anything else you can think of. The Oregon coast is beautiful and motels are not so expensive now that school is starting again. There is good train service from Seattle to Portland and good bus service in Oregon. You can ride a bus from Portland to the Oregon coast with no problem.
Seattle is a larger and probably more interesting city and it is beautifully situated on a "Sound" off the ocean. My guess is that motels here are very cheap by UAE standards.
