Coming by way of Theme Park Insider is more information on the expansion heading to Tokyo Disney Sea and Disneyland.
I find most interesting that Disney is adding an entire themed port devoted just to Frozen. Writer Robert Niles speculates that:
Although Tokyo Disney is promising original attractions and restaurants in these new developments, there are some similarities to existing and upcoming Disney theme park attractions elsewhere. Walt Disney World is currently converting the old “Maelstrom” ridein the Norway pavilion at Epcot into a Frozen-themed ride. The concept art for Tokyo’s Nordic port evokes some of the details found in Epcot’s Norway pavilion, including the Stave Church that can be seen at the bottom of the image.
There are some elements that are similar to Norway’s pavilion, but I don’t think we will be seeing the creation of Anna and Elsa’s castle in Epcot or the addition of Elsa’s Ice Palace that can be seen in top right portion of the concept art. This looks pretty great so far.
Head on over to Theme Park insider to see more concept art of the expansions areas coming to Tokyo Disneyland’s Fantasyland.
