If cruise lines thought that route would be popular enough to warrant doing it, they'd probably already be doing something like a san diego to vancouver route.
I agree with this. There are a couple coastals that Princess does each year and the ability to only stop at US ports wouldn't suddenly make them so popular as to add many, if any, weeks to the rotation. All it would really do is allow the cruise lines to reposition directly to Seattle, without doing the Vancouver trip and then the overnight back to Seattle.
