I have heard rumors of this but I'm not sure how solid they are. I imagine Disney is scrambling to get as much Frozen into the park as possible right now to milk that cash cow. I heard on another podcast that an Imaginear had proposed an "Ice Queen" attraction long before Frozen had been thought of. The description I heard resembled the Elsa Ice Castle scene. The attraction was poo pooed. I bet Disney big wigs are kicking themselves over it now.
