Did this excursion a few times..Loved it. Got to see a whole bunch of a small portion of the interior, without hiring a plane. Worth every $$...you can ride between the cars and take 1000's of pics if you like, grander than the glaciers on the inside passage (or whats left of them I should say). ...but...at one point, you're in Canada...so for the 20 miles you can now ride, they can keep it. Not that we're going up there anymore, but caveat emptor.
