About time! Tokyo, while keeping on top of entertainment refreshes and running on a lot of goodwill, has been pretty lax this decade with new attractions.
Small World moving to Disney Sea though......? That sounds like the eternal fanboi dream of moving it to Epcot.
It is however consistent with height test balloons from the Spring, which never quite made sense to me as there is no real space there without ripping out an attraction. Splash, Haunted Mansion and Pooh are clearly not going anywhere anytime soon, so Small World + Queen of Hearts Banquet Hall makes sense.
