Restructuring Cost And Reserve [Line Items]
Restructuring costs, description				In August 2018, the Company announced a restructuring program (the “2018 Restructuring Program”) focused on reducing costs, improving operating margins and streamlining its management structure to create efficiencies and better align with its strategic business objectives.  The 2018 Restructuring Program involved the elimination of approximately 125 positions during the third quarter of 2018 across the Company’s theme parks and its corporate headquarters. As a result, during the nine months ended September 30, 2018, the Company recorded approximately $5.5 million in pre-tax restructuring charges primarily related to severance and other termination benefits, of which, $3.8 million was incurred during the three months ended September 30, 2018, which is included in restructuring and other separation costs in the accompanying unaudited condensed consolidated statements of comprehensive income. The Company will not incur any additional costs associated with the 2018 Restructuring Program in 2019 as all continuing service obligations were completed as of December 31, 2018.
