During the power outage, Disneyland had said that it was accepting visitors only for re-entry.
An issue with a transformer that supplies power to the Toontown and Fantasyland areas in the park caused the outage.

Select offerings are now available such as Toontown and "it's a small world" Holiday.- Disneyland Today (@DisneylandToday) December 27, 2017
The theme park, which calls itself "The Happiest Place on Earth," draws tens of thousands of visitors each day.
Popular rides including "Pirates of the Caribbean" and "Finding Nemo" were all affected, said Los Angeles resident Ashoka Thiagarajan, who was visiting with his wife and two children.
"It's a huge disappointment. This is my mom's Christmas present to all of us. This has been in the making since August," said Thiagarajan, who was stuck inside "Pirates of the Caribbean" for some 20 minutes.
"How's Disneyland gonna have a power outage the day we paid $124 for peak day tickets?" one visitor tweeted.
The Disney California Adventure theme park was unaffected by the outage, the park said in a tweet.
