Prior to the construction project that is going on at the Palace, there was a lot of back and forth going on regarding whether or not the project could be a thing or not. And, keep in mind, it was initially set to start after American in Paris.
That said, Disney wanted the Palace for Frozen. But, Nederlander was still waffling as to whether or not they could still do the construction project or not. Disney got annoyed with the Nederlander’s waffling back and forth, and eventually told them to either give them an answer or they will take their business elsewhere. That was exactly what they did, hence Frozen being in the St. James
