Companies who (...) run fun parks are not going to be places for real IT wizards to shine.
Sure, if you're talking about some guy in a greasy mac running the Wonderwheel, you're right. But do you have any idea how many (and, simply, HOW) computers are used @ Disney? "Haunted Mansion", as a simple example, has a computer-controlled "drop" that is randomized for start time in the narration, amount of shake, duration, etc., so that it's impossible for someone who has ridden before to anticipate. Also, at least a part of Disney Animation -- which is largely CG -- used to be in Florida, and I assume that it still is. So you're talking rendering, storing, and accessing some pretty big data files. Their data center is critical to Disney's operations.
