So, because an overlay of the Norway pavilion is the cheaper option, that makes it more palatable, even if the furor over Frozen subsides? Good to know....Putting a Frozen attraction in Fantasyland would require an expansion and hundreds of millions. Expanding the park would be the most expensive part.
7DMT is a single attraction placed in a pre-existing expansion. To add Frozen, an entire area could have to be cleared and added to the park.
