I have no problem with Disney tracking me on their property while I am there. Do we know what happens to the fingerprints and photos after we leave? In isolation, the Disney tracking is innocuous even cool, but it comes with risk that the data will be stored / forwarded to entities of which we are unaware. Sorry if I am unnecessarily alarmist. I visited Disney back a few years ago (pre Snowden) and mortified my wife by declining the fingerprint tracking (had to talk with a 'supervisor'). I am not sure you can decline these days.
