Thing is, you say its outdated but then the Jumbos are key important rides at all the Disney Magic Kingdom parks so there quite clearly is a draw there. The problem with Jumbos is something that lies through every Chessington ride. It just isn't looked after. Jumbos could look amazing, everytime they repaint the elephants, they look like new. But they've let the structure fade into a really dodgy green giving the ride this ancient looking edge.As for keeping it, well it is a popular ride. Throughput plays a part in it, but it is terrific for young kids and far more eventful then Sea Dragons or Carousel.
