Again, being the old house one the hill is not just a question of elevation.
Magic Kingdom is not those parks, it has its own unique design.
Being able to walk past something is not the same as it being a weenie. But also, the context isn’t as you present. Disneyland has a different manor design that intentionally downplays the haunted nature but it was also the last major structure along the path when it was built. Payton Manor has a similar siting with spatial separation, there are not multiple paths leading to it. The same mansion structure was intended for Westernland at Tokyo Disneyland but moved to provide a space for Big Thunder Mountain. Tokyo Disneyland also has what is usually considered the weakest placement.
