it may be lazy, but creates a more coherent experience... If I know I am in the Old West and Suddenly I am in a Louisiana Swamp and then in Monument Valley and then in a land of living Automobiles, Portals would be a good way to at least mark a change...especially when all of these areas run together.... Gathering lands around a central Hub with a series of venues to different thematic lands was really the Disney Parks concept... But now as the themes break within the thematic established lands there should also be some way to delineate... If all of the current Frontierland were carefully redesigned to be a Louisiana Riverbend creating a gateway divide as you leave Liberty Square ( just past Golden Horseshoe..that area could make sense and give them the space to turn Tall Tale Cafe into a real Tiana's Palace...and make the Country in Country Bears refer a little less Tennessee and more Louisiana swamp..., but there would need to be some sort of visual device taking you from the swamps of Louisiana to Monument Valley and then to Carsland Piston Peak area...and one more for Villains Land if and when that comes online. The other lands don't seem to need a dividing device as much as the back half of the park will to make some visual sense....
