Timberline lodge on Mt. Hood was where Jack Nicholson filmed "The Shining" - I haven't been there but Mt. Hood is beautiful.
If you're going down to Crater Lake or Oregon Caves area, there are also jet boat rides available on the Rogue River. We're planning that this summer with our kids.
If you're up north of Seattle, there's a little town called La Connor WA which several years ago was a great kinda artsy place to shop - I'd bet there's a quilt shop there.
