One cool thing about Seattle is how close it is to Canada. One of my favorite trips was one where my wife and I spent a couple of days in Seattle, and then went North into Canada, saw Victoria Island, spend a couple of days in Whistler, and then road tripped across western Canada, all the way across the Rockies (we lingered in Banff and Lake Louise) to Calgary, staying in B&B's along the way. Not sure if it is still the case, but B&B's were cheaper AND nicer than even low-end motels in that part of Canada, which made it a no-brainer. Anyhow, if this sounds interesting and you want to know more, let me know.
