Can you sail? There is someone on Craigslist advertising bareboat or captained sailing in puget sound for somewhat reasonable pricing. If so, lots of campgrounds take boats. It would also be a different way to experience the sound.

Yes. A week in the San juans is doable. Any combo really works but limit seattle driving. It sucks.

I would skip the "must see" tourist stuff. I would see natural wonder type stuff. Mt. Saint Helens is remarkable- and not too far off. I would focus on things that are not in your normal life. Example? I took some swedes to the Oregon Desert for some trout fishing once. They loved it as they have mountains and ocean in Sweden. Desert was novel.

Welcome and enjoy!
