Thanks so much for all the great ideas. Let me ask this: has anyone taken the train from Seattle to Vancouver?
I have read some view it as advantageous to rent a car in Vancouver and avoid the border delays with a vehicle...
I grew up here in Seattle and once took the train with my family in tow for a cruise from Vancouver. All the luggage, and generations of family, it still was worthwhile. We flew back from Anchorage and did not want to deal with parking so far north. The train station in Everett worked well for us that trip, but it was 12 years ago. Last cruise with our family was RT port of Seattle, and we taxied down to the pier cheap.
There are tricks to going across the border by car, we always take the Bellis Fair exit off of I-5 and cross over due north of Bellingham at Lynden. Hardly ever a wait. The Blaine and Peace Arch crossing can be a bear without a Nexus card.
