California Adventure Ferris wheel riders were stranded for about 90 minutes in high heat on Thursday after a ride broke down.
A statement from Disneyland said that Mickey's Fun Wheel was experiencing technical difficulties and that riders were removed from the 150-foot-high wheel.
Around 30 riders were evacuated, with the last exiting around 6 p.m., The Orange County Register reported.

No injuries were reported.
"The safety of our guests and cast members is our highest priority," Disneyland said in a statement.
It's the second such problem in recent months at the theme park.
Riders had to be escorted off the California Screamin' roller coaster in July after the ride stopped due to a technical problem, a park spokesman said. Nobody was hurt.
