Power went out for more than an hour and a half at Universal Studios in Orlando, forcing passengers to be evacuated from the Men in Black and Transformers rides.
Universal spokesman Tom Schroder said that the cause of the power outage Friday was still being investigated. There were no injuries.
Schroder says guests coming to Universal Studios were diverted to its sister theme park next door, Islands of Adventure, which never lost power.
The Orlando Fire Department was called to assist with the evacuations. Orlando Fire Department spokeswoman Ashley Papagni says there were no reports of ride passengers in distress.
Firefighters also checked elevators to make sure no one was stuck.
