Leaving for the train from Seattle to Vancouver yesterday, for example, I had ample time to take light rail from UW to the King Street Station, do passport check, and get seated. But it turned out that light rail was closed between UW and downtown, and I had to take a courtesy shuttle bus instead. All my enjoyable travel time (coffee at the station) got eaten up by the shuttle bus. I barely got through passport check with enough time to get through the gate and onto the train.
