We just booked this-Zaandam departing San Diego 4/20. Stopping at Victoria, Vancouver, Astoria, Seattle and then Vancouver again. The reason for the circuitous route is to set up Zaandam's Alaska schedule beginning May2 out of Vancouver. We are planning on visiting elderly family members in Spokane. Connections from Seattle to Spokane are much easier than from Vancouver to Spokane so we'll just hope for the best. Since we'll be hitting two non U.S. ports before arriving at Seattle I don't know why this would present a problem.
