If they don't leave Vancouver until after 11 am how can they possibly reach Seattle in 3 hrs? Ships don't do freeway speeds. On our itinerary it shows that our ship is scheduled to depart at 1 am the next morning not the normal around 5 pm time. So they apparently know they need extra time for boarding passengers and provisions.
So does anyone have an idea on the real time frame. If actual boarding ends up being 6 pm or later they will lots of angry people who have been sitting in the terminal for hours waiting to board a ship that hasn't yet arrived.
