One crazy idea I had was for a law requiring anyone using tracking technology to post a sign in front of each device large enough to be read by anyone
whose position was being tracked. (Think of signs posted at the theme park entrances, entrances at each attraction with RFID readers, etc. "Your location information is being recorded.") Do that at WDW and the public very quickly would demand something be done.
The government wouldn't even have to step in. Once people realized how closely their positions were being monitored, enough might be "creeped out" to cause a drop in attendance, forcing Disney is take them out on their own.
Corporations often don't want you to know what they are doing because it hurts business. Simply require them to disclose what they are doing and they quickly learn it's financially not worth doing.
