We are taking quickcoach. They have a direct bus from the cruise terminal to downtown Seattle and then on to the airport. You can call them. They are super helpful.
if you don't mind me asking, what time is your seattle flight? i'm worried about the border crossing taking too long and missing the flight. i think the bus has to empty at the border, and that border crossing lines can be long. the flight needs to be on monday (the day we dock). what time do y'all think would be a safe time for the flight?
