We just received the following from a Disneyland spokesperson regarding the unscheduled closure of Alice in Wonderland:
During an unrelated visit to the park, a Cal OSHA representative observed a maintenance cast member on the track of the Alice in Wonderland attraction and made us aware of a potential safety issue. We agreed with the opportunity to enhance safety and voluntarily took down the attraction until modifications can be made.
An interim solution — likely scaffolding or another acceptable barrier — will be erected on the exterior “vine” area of the track, which will enhance cast safety. It should be in place within the next few weeks.
