It's the main cruise ship dock, but not the only one. The other dock is Ballantyne pier. Check with your cruise line or this link http://www.portvancouver.com/vanAlaCruise/...edule/index.php? to determine which is the correct pier. In general, ships from Royal Caribbean and Celebrity use Ballantyne; everyone else uses Canada Place.
Check the hours for the train. I think there's only one train a day, and it may bee to late for connections with your cruise on the day of the cruise.
Thanks for the link, Zaandam leaves from Canada Place! So we'll either take Amtrak or Quick Shuttle from SEA to Canada Place. Either leaves pretty early in the morning so we'll get to pier before 1pm.
Then from Seward to Anchorage, we'll take the train to enjoy scenary on the way.
Now all that's left is to book the excursions. Appreciate everyone's help!
