They were recently banned from being used on attractions, as the sticks pose a safety issue. (Sticking items outside of a ride vehicle is prohibited.) Now, if all goes as the sources say, Security will keep guests from taking the sticks past the gate. Guests will be given the option to either leave and take their Selfie Stick or check it with Guest Relations and pick it up when they leave.
The ban in Disney’s United States Parks begins on Tuesday, June 30th. July 1st is the start date for the ban in Disneyland Paris and in Hong Kong.
