Accounting Changes And Error Corrections [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2012 included in the Company’s prospectus as filed with the SEC on April 18, 2013, pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended (the “Securities Act”). The unaudited condensed consolidated balance sheet as of December 31, 2012 has been derived from the audited consolidated financial statements at that date. In the opinion of management, such unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations for the year ending December 31, 2013 or any future period due to the seasonal nature of the Company’s operations. Based upon historical results, the Company typically generates its highest revenues in the second and third quarters of each year and incurs a net loss in the first and fourth quarters, in part because six of its theme parks are only open for a portion of the year. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, including SEA. All intercompany accounts have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions include, but are not limited to, the accounting for self-insurance, deferred tax assets, deferred revenue, equity compensation and the valuation of goodwill and other indefinite-lived intangible assets. Actual results could differ from those estimates.
Recently Issued Accounting Pronouncements	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-02, “Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which amends Accounting Standards Codification (“ASC”) 220, Comprehensive Income. The amended guidance requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. Additionally, entities are required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amended guidance does not change the current requirements for reporting net income or other comprehensive income. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. The adoption of ASU No. 2013-02 did not have a significant impact on the Company’s condensed consolidated financial statements.
