To be honest, why would they need escalators for the main entrance? Everything's flat bottom, so it makes no sense putting the escalators in.
Assuming it'd be the Osaka version in a sense, with the esclators; it'd be as a means to get people up from the point of entrance to the land, into the plaza next to Princess Peach's castle.
My curiosity, would be if the main exit of SNW for the time being, will then be the hallway in-between the restrooms and Jurassic Cafe; considering how Orlando had proper exits in mind for the land in the Kidzone version.
