For what it's worth, I don't think Disney has any intention of trying to convince us any further that the ride belongs in Norway. They're going to put it there. Staggs has already given the Company's explanation. It doesn't convince most of us here. It will convince many others. And many others won't care.
Heck, Frozen is closer to belonging in Norway than Aladdin is to belonging in Morocco (which is only about 3,000 miles from Saudi Arabia, and at least 2,500 miles from anything associated with the arabian desert.
The ride could still be a huge triumph -- I really think Disney will try to make this one a great "ride through the movie", but I don't think they'll do anyting more about making it fit in Norway.
I have a small dream that somebody will win TDO or Imagineering over with a proposal to add more grounded content to all the WS pavilions that lack it -- exhibits and information on the history, art, economy and culture of the countries. If they choose to do so, the first room of the queue would make a wonderful place for a slideshow/movie/multimedia presentation with narration about Norway. Something we see and hear as we wait, much like the reel of movie trailers in GMR. Then the second room would start the "Frozen" content of the queue -- chapter 1 of the story of the ride, as it were, explaining how the history and culture of the area inspired the story (that'd be a stretch) before introducing us to the characters.
But I do not in any way think that it will happen, nor would it cure the bad placement of the ride if it did.
