The park will offer $99 annual passes for 2021, matching the price when the park opened in 2011.
The event will run on weekends in October, but be warned: costume masks don't meet Legoland's face mask requirements.
The rule change is due to the city of Winter Haven, Florida passing a face mask ordinance on Monday.
The Winter Haven resort declined to specify the number of layoffs or which departments were affected.
Legoland indicated it will continue to provide free face masks to guests, but will not require them to be worn like other Florida theme parks.
Unlike Disney World and Universal Orlando, Legoland Florida is not requiring guests to wear a face mask or covering when it reopens on June 1.
The two parks are taking different approaches to face masks: Universal will require guests to wear them, while Legoland will only recommend them.
"There is material uncertainty on our ability to continue as a going concern," Merlin Entertainments said in its annual report.
