#1 Vancouver is all one word ( Not VanCouver )
#2 Yes Seattle is a port call
#3 Seattle is about 2 hour drive from Vancouver
#4 You knew the ship's itinerary was San Diego to Vancouver Why did you book the trip if you only want to go as far as Seattle?
#5 The shuttle from Port of Vancouver to Port of Seattle is $26 USD
#6 You can ask special permission from the captain of the ship to disembark in Seattle, however because of the passenger services act I doubt he will allow it.
