I've did Portland-Seattle-Vancouver about a decade ago, which was nice. It's not fast but you don't want it to be if your objective is to see the scenery. Much of the route hugs the coast so make sure you're on the water facing side of the train if you don't want to spend a lot of the day looking at a wall of trees. At that time they didn't have one day through service between Portland and Vancouver but spending an afternoon and night in Seattle was nice since I'd never been there before. When booking you just have to make sure you don't accidentally sign up for the Amtrak bus that runs on the same route. Not sure if service into Canada has been restored yet.
