Accounting Policies [Abstract]
Description of the Business and Basis of Presentation	Description of the Business SeaWorld Entertainment, Inc., through its wholly-owned subsidiary, SeaWorld Parks & Entertainment, Inc. (“SEA”) (collectively, the “Company”), owns and operates twelve theme parks within the United States. Prior to its initial public offering in April 2013, the Company was owned by ten limited partnerships (the “Partnerships” or the “Seller”), ultimately owned by affiliates of The Blackstone Group L.P. (“Blackstone”) and certain co-investors. As of March 31, 2017, the Partnerships own approximately 21.5% of the Company’s total outstanding common stock. On March 24, 2017, the Company announced that an affiliate of Zhonghong Zhuoye Group Co., Ltd. (“ZHG Group”), Sun Wise (UK) Co., LTD (“ZHG” or “Buyer”) entered into an agreement to acquire approximately 21% of the outstanding shares of common stock of the Company (the “Sale”) from Seller, pursuant to a Stock Purchase Agreement between ZHG and Seller (the “Stock Purchase Agreement”). The Sale closed on May 8, 2017. See further discussion in Note 9–Related-Party Transactions and Note 12–Stockholders’ Equity. The Company operates SeaWorld theme parks in Orlando, Florida; San Antonio, Texas; and San Diego, California, and Busch Gardens theme parks in Tampa, Florida, and Williamsburg, Virginia. The Company operates water park attractions in Orlando, Florida (Aquatica); San Antonio, Texas (Aquatica); San Diego, California (Aquatica); Tampa, Florida (Adventure Island); and Williamsburg, Virginia (Water Country USA). The Company also operates a reservations-only theme park offering interaction with marine animals in Orlando, Florida (Discovery Cove) and a seasonal park in Langhorne, Pennsylvania (Sesame Place). 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 (“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, 2016 included in the Company’s Annual Report on Form 10-K filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2016 was derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K. 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, 2017 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 seven 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. The Company reviews new accounting pronouncements as they are issued or proposed by the Financial Accounting Standards Board (“FASB”). Recently Implemented Accounting Standards In January 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-04, Intangible–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU removes step two from the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment charge would now be determined based on the comparison of the fair value of a reporting unit to its carrying value, not to exceed the carrying amount of goodwill. This guidance is effective starting with a company’s interim or annual goodwill impairment tests in fiscal years beginning after December 15, 2019 and must be applied on a prospective basis. Early adoption is permitted for interim or annual impairment tests performed after January 1, 2017. The Company has elected to adopt ASU 2017-04 as of January 1, 2017 and will follow this guidance on any interim or annual impairment tests performed in fiscal year 2017. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. This ASU simplifies several aspects of the accounting for share-based payment transactions (Topic 718) including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as the classification of related amounts within the statement of cash flows and the classification of awards as either equity or liabilities. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company adopted this ASU effective January 1, 2017. ASU 2016-09 requires a policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur. The Company elected to change its policy to recognize the impact of forfeitures as they occur and determined the cumulative impact of this change was not material as of January 1, 2017. ASU 2016-09 also requires cash paid by an employer when directly withholding shares for tax withholding purposes to be classified as a financing activity and excess tax benefits to be classified as an operating activity in the accompanying unaudited condensed consolidated statement of cash flows, which does not differ from the Company’s historical treatment of these items. Additionally, ASU 2016-09 requires the tax effects of exercised or vested awards to be treated as discrete items in the reporting period in which they occur, which was applied prospectively, beginning January 1, 2017 by the Company. Recently Issued Accounting Standards In November 2016, the FASB issued ASU 2016-18, Restricted Cash–a Consensus of the FASB Emerging Issues Task Force. This ASU aims to reduce the diversity in practice of the presentation of changes or transfers in restricted cash flows on the statement of cash flows. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling beginning and ending total amounts on the statement of cash flows for the period. The guidance is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those annual reporting periods with early adoption permitted and should be applied using a retrospective transition method. The Company does not expect a material impact upon adoption of this ASU to its unaudited condensed consolidated statements of cash flows or unaudited condensed consolidated balance sheets. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. ASU 2016-16 simplifies the income tax accounting of intra-entity transfers of an asset other than inventory by requiring an entity to recognize the income tax effect when the transfer occurs. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods and early adoption is permitted. The Company does not expect a material impact upon adoption of this ASU on its unaudited condensed consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. This ASU provides guidance on the presentation and classification of eight specific cash flow issues that previously resulted in diversity in practice. The ASU will be effective for annual periods beginning after December 15, 2017 and interim periods therein, with early adoption permitted and should be applied using a retrospective transition method. The Company has not yet adopted this ASU but does not expect a material impact to its unaudited condensed consolidated statements of cash flows. On February 25, 2016, the FASB issued ASU 2016-02, Leases. This ASU establishes a new lease accounting model that, for many companies, eliminates the concept of operating leases and requires entities to record lease assets and lease liabilities on the balance sheet for certain types of leases. Under this ASU, an entity is required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable financial statement users to assess the amount, timing and uncertainty of cash flows arising from leases. The ASU will be effective for annual periods beginning after December 15, 2018, and interim periods therein. Early adoption will be permitted for all entities. The provisions of the ASU are to be applied using a modified retrospective approach. The Company has not yet adopted this ASU and is currently evaluating the impact of this ASU on its unaudited condensed consolidated financial statements. Upon adoption of this ASU, the Company expects its San Diego land lease, among other operating leases, to be recorded as a right-of-use asset with a corresponding lease liability. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Topic 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date to annual reporting periods beginning after December 15, 2017 using one of two transition methods, either retrospective or a modified retrospective transition method which calculates a cumulative-effect adjustment as of the date of adoption, with earlier adoption permitted for annual periods beginning after December 15, 2016. During 2016, the FASB issued four updates to the revenue recognition guidance (Topic 606), ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net), ASU 2016-10, Identifying Performance Obligations and Licensing, ASU 2016-12, Narrow-Scope Improvements and Practical Expedients and ASU 2016-20, Technical Corrections and Improvements. The Company plans to adopt this guidance in the first quarter of 2018 using a modified retrospective transition method. The Company has been closely monitoring developments related to this new standard but has not yet completed its evaluation of the accounting and disclosure requirements on its unaudited condensed consolidated financial statements. The Company is reviewing current accounting policies and practices to identify changes that would result from applying the requirements under the new standards. Based on the Company’s analysis to date, it does not anticipate a material impact on the timing of revenue recognition upon adoption; however, the Company expects an impact on the classification of revenue between admissions revenue and food, merchandise and other revenue. The Company also expects revenue recognition disclosures will include additional detail in accordance with the new requirements.
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 unaudited 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.
Segment Reporting	Segment Reporting The Company maintains discrete financial information for each of its twelve theme parks, which is used by the Chief Operating Decision Maker (“CODM”), identified as the Chief Executive Officer, as a basis for allocating resources. Each theme park has been identified as an operating segment and meets the criteria for aggregation due to similar economic characteristics. In addition, all of the theme parks provide similar products and services and share similar processes for delivering services. The theme parks have a high degree of similarity in the workforces and target similar consumer groups. Accordingly, based on these economic and operational similarities and the way the CODM monitors and makes decisions affecting the operations, the Company has concluded that its operating segments may be aggregated and that it has one reportable segment.
Property and Equipment-Net	Property and Equipment—Net During the first quarter of 2016, the Company made a decision to remove deep-water lifting floors from the orca habitats at each of its three SeaWorld theme parks. As a result, during the three months ended March 31, 2016, the Company recorded approximately $33,700 of accelerated depreciation related to the disposal of these lifting floors, which is included in depreciation and amortization expense in the unaudited condensed consolidated statements of comprehensive loss. During the three months ended March 31, 2016, the Company also recorded approximately $6,400 in asset write-offs associated with its previously disclosed orca habitat expansion (the “Blue World Project”) as the Company made a decision to not move forward with the Blue World Project as originally designed and planned.
Revenue Recognition	Revenue Recognition The Company recognizes revenue upon admission into a park for single day tickets and when products are received by customers for merchandise, culinary or other in-park spending. For season passes and other multi-use admission products, deferred revenue is recorded and the related revenue is recognized over the terms of the admission product and its estimated usage. Deferred revenue includes a current and long-term portion and is included in deferred revenue and other liabilities, respectively, in the accompanying unaudited condensed consolidated balance sheets. As of March 31, 2017 and December 31, 2016, other liabilities also includes $10,000 in deferred revenue related to nonrefundable funds received from a partner in connection with a potential project in the Middle East (the “Middle East Project”) to provide certain services pertaining to the planning and design of the Middle East Project, with funding received expected to offset internal expenses. Approximately $2,700 of costs incurred related to the Middle East Project are recorded in other assets in the accompanying unaudited condensed consolidated balance sheet as of March 31, 2017. The Middle East Project is subject to various conditions, including, but not limited to, the parties completing the design development and there is no assurance that the Middle East Project will be completed or advance to the next stages. On March 24, 2017, the Company entered into a Park Exclusivity and Concept Design Agreement (the “ECDA”) and a Center Concept & Preliminary Design Support Agreement (the “CDSA”) (collectively, the “ZHG Agreements”) with Zhonghong Holding, Co. Ltd. (“Zhonghong Holding”), an affiliate of ZHG Group, to provide design, support and advisory services for various potential projects and granting exclusive rights in China, Taiwan, Hong Kong and Macau (the “Territory”). Under the terms of the ECDA, the Company will work with Zhonghong Holding and a top theme park design company, to create and produce concept designs and development analysis for theme parks, water parks and interactive parks in the Territory. Under the terms of the CDSA, the Company will provide guidance, support, input, and expertise relating to the initial strategic planning, concept and preliminary design of Zhonghong Holding’s family entertainment and other similar centers. The Company recognizes revenue under the ZHG Agreements on a straight-line basis over the contractual term of the agreements. Due to the effective date of the ZHG Agreements, related revenue during the three months ended March 31, 2017 was not material. See further discussion in Note 9–Related-Party Transactions. The Company has also entered into agreements with certain external theme park, zoo and other attraction operators to jointly market and sell single and multi-use admission products. These joint products allow admission to both a Company park and an external park, zoo or other attraction. The agreements with the external partners specify the allocation of revenue to the Company from any jointly sold products. Whether the Company or the external partner sells the product, the Company’s portion of revenue is deferred until the first time the product is redeemed at one of its parks and recognized over its related use in a manner consistent with the Company’s own admission products. The Company barters theme park admission products and sponsorship opportunities for advertising, employee recognition awards, and various other services. The fair value of the products or services is recognized into admissions revenue and related expenses at the time of the exchange and approximates the estimated fair value of the goods or services received or provided, whichever is more readily determinable.
