Gaston family were on a day trip to Magic Kingdom when they made discovery
Madison, 17, and her mother, Jennifer, only found out about the AirTag four hours after they were first tracked
They went back to the theme park’s parking lot before searching their car for the device, but to no avail
Madison continued to monitor the device’s location on her iPhone through the remainder of the day
Mother and daughter alerted police but still don’t know who the gadget’s owner is
Hundreds of women across the U.S. have reported receiving notifications about AirTags they do not own tacking their every move
The devices can easily be hidden and report movement to owner’s iPhone
