Have you noticed the discrepancies between wait times on Genie and what’s posted in the parks? It’s not because Disney doesn’t know what’s posted at the queue wait time board.
Disney has been doing this for years when it comes to pricing and availability of resort rooms. They use cookies to track your behavior across their sites and assess your likelihood of booking. Then they show you pricing and availability based on that information.
If they can identify you further (which Genie does), they then factor in past trip behaviors (your likelihood to pay a bit more for a moderate resort room or for ILL, for example), your Disney+/Hulu/ESPN/ABC viewing history, demographic info, etc., and then adjust what it shows you accordingly in order to try to influence your behavior.
I’d encourage you to check out Disney’s
Company-wide Privacy Policy and their
Online Tracking policy statement.
