Pink line is going straight to Echo Lake. I don't care that you have to walk around to get to IJ, that whole area is Echo Lake (just like you have to go through a long part of Adventureland to get to any attractions). The Orange line goes to Mickey Ave. (and yes, there is a direct entrance, not just a wall).Nor does your pink marker lead anywhere but to a lake you have to walk around to get to something else. I realize its been a year since I visited, but I'm not sure where your going with your orange line, other then through a wall.
So was Expedition Everest, does that say anything about it? Everything that opened after opening day can be considered an afterthought.It's not an opinion that it was an afterthought added to the park years later.
Does this map not prove that you can get to all lands via the hat area?
