At least eight cars caught fire at a Disneyland parking structure Monday night, injuring park staffers, prompting some evacuations and causing nearly $180,000 in damage, authorities said. During the blaze, seven Disney employees suffered minor injuries from smoke inhalation, four of whom were taken to the hospital, said Sgt. Daron Wyatt, a spokesman for the Anaheim Police Department. No foul play is suspected, and the cause of the fire is under investigation. The fire was reported just before 4:40 p.m. on the second floor of the Mickey & Friends parking garage, a six-level structure off Disneyland Drive near the northwest corner of Disneyland Park, Wyatt said.
