Travel Portland, Seattle or Vancouver or a combination?

If you get a chance in the future, take a drive along the Pacific Coast Highway (stunning!). Also hit Astoria, Oregon. There are some amazing bed and breakfasts there. Lovely.

To be honest, I've never been a huge Seattle fan. Probably because there are some cooler places to visit in the northwest. Fairhaven near Bellingham, has always been one.
I will check out these ideas as well. Thank you for the input!
