"Walt Disney World is banning selfie-sticks from its theme parks because selfie-sticks have become a growing safety concern for both our guests and cast." Disney World spokeswoman Kim Prunty said. Under a new policy, which takes effect Tuesday, the poles won't make it past the bag check at any Disney World theme park. The sticks also won't be allowed in Disney World water parks or Disney Quest, a gaming attraction at Downtown Disney. Selfie-sticks will also become forbidden at Disneyland Resort in California on June 30. The prohibition begins at Disney's parks in Paris and Hong Kong on July 1. Guests will be checked for the equipment during the routine bag check that happens near the parks' entrances. They will have an option of turning in their selfie-sticks for pick-up later or to go back to their cars or hotel rooms to keep them. Visitors will be told of the policy in locations such as the parking lots and at the resort's hotels. The prohibition will be added to the park rules post on Disney World's website. The issue has been building at Disney. Previously, the sticks were prohibited from its rides, and "no selfie-sticks" signs were at select rides, such as Big Thunder Mountain Railroad at Magic Kingdom. Cast members have given oral warnings to rule breakers. Selfie-stick users put smartphones and cameras on the ends of poles to extend their reach, frequently capturing theme-park moments through self-portraits. The tools have been banned in public places - including some museums and stadiums - worldwide for _ views or causing safety issues. Disney World already prohibits items such as skateboards, inline skates, wagon, folding chairs and glass containers, according to its official website, which also lists "other items that we determine may be harmful." Universal Orlando has banned selfie-sticks and other loose items from certain thrill rides at Universal Studios and Islands of Adventure theme parks, but it has not set parkwide bans.
