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
