Well, Norway did "inspire" the film's look and feel (the Stave Church is filled with a presentation on just that.)
Also, I don't know that we need a whole land devoted to Frozen, and a land full of just a mishmash of IP would not be a good solution either.
I was referring to EPCOT when I mentioned that they tried not having characters before and most complained.
Seriously though, I for one want to see Remy in France, Mary Poppins in UK, the 3 Caballeros in Mexico, etc. I like seeing both cultural representations of the country and having it spiced up with other attractions using appropriate characters.
AND
I know that Disney does lots and lots of research. You are welcome to your opinion, but you can be pretty sure that you are in the minority based on the research they have conducted.
