It may be the happiest place on Earth, but the Magic Kingdom has become a little more restrictive(限制的) for the children hoping to enjoy Disney’s US parks on their own. Beginning on March 23 of this year, anyone under the age of 14 must go there with someone over 14. If a worker who works at the front gates sees a child who looks younger than 14 without a person who looks older than that, he will have a talk with the tourist. If he is sure the tourist is under 14, his parents will be contacted to pick them up.
Before this, Disney did not have any age restrictions(限制) for tourists. The new rule was set up after Disney conducted a survey of its tourists and contacted various child welfare association(福利机构). They both thought it was necessary to have the age requirement. The American Red Cross suggested that 14 is the minimum(最小的) age for babysitters(保姆).
News of the age restriction comes nearly a week. A child on vacation with his father and mother fell into a pool and died at Disneyland Pop Century Resort(度假村). Anthory Johnson was swimming in the hotel pool with a group of children including his little brother and a cousin at about 9:30 pm when the accident happened. Witnesses said the teen was playing in the water on Sunday evening without family members. A cousin found him under water around 9:10 pm and told others in the group who pulled him out of water. Orange Country Sheriff’s officials said after Anthony was taken to nearby hospital, he died several days later.
