I have no idea why you'd do this, but unless it resets I'd assume the Tron at the Art of Animation still has my initials on it somewhere. I spent a little time and money on it and ended up more than doubling the high score to date on the machine.
As for the machines there being broken or whatever and people complaining, remember - these get TONS of play, and the pins are guaranteed the most maintenance-heavy machines they have there. I definitely saw some good work done to some of their pins when I was there - notably, at least one in the contemporary had some tweaks to it to keep it running better including some strategic LEDs which I was really surprised to see - but when the games have people on them pretty darn regularly from open to close, it's hard to maintain them all perfectly working.
Also, Disney has peak seasons with tons of guests and off seasons with far less. It's impossible to hire people especially in that market to do a skilled job like pinball repair cheaply enough for the three or four times of they year they need them the most. Visit in the off season or just as the on-season times start, and you're much more likely to see things in much better operating condition.
With the exception of Disneyquest (I think), I am all but certain that the rest of their equipment is "routed" by an outside operator with an exclusive contract there. Regardless, Disney's quality control at Disney World isn't quite what it used to be or what it is still for the most part at Disneyland. Different markets expect different things, and World draws people much more infrequently who don't generally notice little things that aren't quite perfect, but without going too much into detail, having worked in the industry World shows a lot more wear than Land does. I'd say that the job they do maintaining their pins is actually really solid.
