Seattle/Olympic NP/Vancouver or Banff/Jasper NPs/Vancouver

We are hoping to fly west this summer. We are entertaining a couple of options. Both would include going to the Vancouver area. One would be to fly to Seattle, drive to Olympic NP and the San Juan Islands and then fly back from Boston. The other would be to fly to Calgary, go to Banff and Jasper (have been to both before but our son hasn't), fly from Calgary to Vancouver, tour that area, then fly from Vancouver to Boston. We'd have two weeks. Interests are just about everything-hiking, biking, boating, fishing, wildlife, shopping, historical-but more of an emphasis on outdoor activities. Budget not-withstanding, I'm interested in preferences and why as well as what to do. Thanks!
