There is a shuttle bus with Quick Shuttle, $41 pp Canada Place to Seatac. Can be dropped off downtown too. Since you are 140 miles away a limo would be costly, I recall, vaguely about a $300. trip?? there is also Amtrak, but I mostly drive, easy to pick up a downtown Vancouver car and drop off at Seatac. Handy with several layover hours if on a red eye flight.
