Disney has been increasing security measures at the parks and in other areas on property, like Disney Springs. It looks like they are set to get even more law enforcement.
Disney has been adding more security in an effort to make sure guests have a safe experience. They added metal detectors at the park entrances in December 2015 and now they are adding more security.
Disney has been doing a lot of tightening of their security recently. With everything that has been going on in the world, it’s no surprise that they would want to do this in an effort to keep their guests safer.
