Walt Disney World is tightening its security and has installed(安装) metal detectors（探测器）at the entrance to all four of its theme parks.
The move follows a man who tried to bring a gun into the Magic Kingdom at Walt Disney World. Visitors to the parks will be selected for screening. SeaWorld and Universal Studios are also expected to increase their security measures today.
“It’s no real surprise that Disney and SeaWorld would install metal detectors in the current situation, and we expect Universal Orlando to follow suit,” said Simon Veness, our Florida expert. “They are already the norm(标准，惯例) at sporting field in the US, while Universal used them in the past for special events at each of their big rollercoasters, to prevent mobile phones, etc., from flying out of pockets on the ride. None of the parks have announced if this will be a lasting arrangement, but we would expect it to stay in place all the time when terrorism remains a key concern in much of the world.”
He said that the Six Flags parks, also popular throughout America, had used metal detectors for a number of years.
“All the parks have a basic bag-check operation for the past 14 years and this really only makes a more formal process,” he added. “It might slow down entry to the parks slightly, but we expect the process to be pretty efficient once installed.”
