We will be spending a week in Glacier NP and wondered if we should take 2 days just to drive the icefields parkway? I know it is LONG and it would be a drive/stop for photo op only trip up, spend the night, return. Is this crazy? I know it will be about a 10 hour trip so hiking is out of the question. Is it worth it? Our Canadian passport card expires and we thought as long as we were so close, we'd maybe go ahead and get a "taste" of the area.
