Essential, shmessential. It's an arbitrary designation. If Universal could continue construction, then why exactly couldn't Disney perform repairs?When Disney shut everything down in March, every single facility was evacuated and virtually nobody was allowed into any building for any reason other than security or critical services. Nobody was authorized to work in the building for many, many months so the most they could do was software work which they could do from home, but nothing could be done inside the building. Maintaining an attraction was not classified as essential services so they just shut it all down until it was deemed safe to return around June sometime when the preparations for re-opening began.
