I'm a US citizen researching a two-week trip to Vancouver this summer. Apparently flights from the east coast of the US to Seattle generally cost about half what it costs to fly directly into Vancouver. Since it's only a three-hour drive between the cities, seems to maje sense to fly into Seattle and proceed to Vancouver form there, only question is what's the best approach? I've seed Quick Shuttle, which at around 6 hours from SeaTac to downtown Vancouver hotels doesn't seem to live up to it'name at all. Grayhound isn't any faster. Amtrak is an option I haven't priced yet, and a one-way car rental was something else I was considering. I say one-way because I think I can get around using public transportation while in Vancouver...a misconception? Thanks for any experienced advice!
