How often did that occur? (A real question and not one borne of cynicism). Back when the earth was cooling, we would routinely walk down to the lower tier of the island to watch Illuminations or its predecessors. I don't doubt that it was sometimes closed to the general public, but we succeeded in getting down there each and every time we went to Epcot. Today, I don't think it is ever an option for the general public. If I am wrong about that, then...nevermind. But if it is never available to the general public anymore, then this would be an example of something that has been "completely removed" from the public's use where once it was "sometimes removed" from the public's use. And same goes for the train station.
