Eventually, the crowd will leave and Disney World will close.  It’s the way things go for amusement parks and other such attractions.  It’s sad seeing them this.  The pictures in the gallery are photoshop, but here’s some real ones.

Abandoned amusement parks are eerie and strange places that get depressing real fast.  Of course keeping an amusement park going takes a great deal of energy and effort, as this anime shows.
