Disney typically adjusts operating hours as attendance levels demand. Throughout the year, Disney will adjust operating hours, typically adding more hours as we approach affected dates. Recently, Disney added hours for select dates in November and December at Disney’s Animal Kingdom. Here’s a breakdown of the adjustments:

• November 25-27, 29: Park closing extended from 8pm to 9pm
• December 31: Park closing extended from 8pm to 12am midnight

Earlier this year, Disney announced that Disney’s Animal Kingdom would be open until midnight on New Year’s Eve, so the change there isn’t unexpected. The November extensions line up with some extended hours at Magic Kingdom as well.
