Organization, Consolidation and Presentation of Financial Statements [Abstract]
Revenue Recognition	The Company’s revenues and earnings are seasonal in nature, primarily due to its Racing Operations segment. Therefore, revenues and operating results for any interim quarter are generally not indicative of the revenues and operating results for the year and may not be comparable with results for the corresponding period of the previous year. For instance, the Company historically has had fewer live racing days during the first quarter of each year, and the majority of its live racing revenue occurs during the second quarter, with the running of the Kentucky Derby and the Kentucky Oaks. The Company conducted 104 live thoroughbred racing days during the third quarter of 2013, which compares to 112 live thoroughbred racing days during the third quarter of 2012. For the nine months ended September 30, 2013, the Company conducted 284 live thoroughbred racings days, which compares to 290 live racing days during the nine months ended September 30, 2012. Furthermore, gaming revenues and earnings have historically been higher during the first quarter due to seasonal revenues from the Company's predominately southern gaming properties.
Customer Loyalty Programs	The Company’s customer loyalty programs offer incentives to customers who wager at the Company’s racetracks, through its advance deposit wagering platform, TwinSpires.com, or at its gaming facilities. The TSC Elite program is for pari-mutuel wagering at the Company’s racetracks or through TwinSpires.com. The Player’s Club is offered at the Company’s gaming facilities in Louisiana, Florida, Maine and Mississippi. As of September 30, 2013 and December 31, 2012, the outstanding reward point liabilities were $2.3 million and $2.1 million, respectively, and were included in accrued expenses.
Promotional Allowances	Promotional allowances, which include the Company’s customer loyalty programs, primarily consist of the retail value of complimentary goods and services provided to guests at no charge. The retail value of these promotional allowances is included in gross revenue and then deducted to arrive at net revenue. During the three months ended September 30, 2013 and 2012, promotional allowances of $8.7 million and $5.2 million, respectively, were included as a reduction to arrive at net revenues. During those periods, Online Business promotional allowances were $3.4 million and $2.4 million, respectively. Gaming promotional allowances were $5.1 million and $2.5 million, respectively. Racing Operations promotional allowances were $0.2 million and $0.3 million, respectively. The estimated cost of providing promotional allowances included in operating expenses for the three months ended September 30, 2013 and 2012 totaled $2.3 million and $1.3 million, respectively. During the nine months ended September 30, 2013 and 2012, promotional allowances of $25.1 million and $14.6 million, respectively, were included as a reduction to arrive at net revenues. During those periods, Online Business promotional allowances were $9.5 million and $6.3 million, respectively. Gaming promotional allowances were $14.9 million and $7.5 million, respectively. Racing Operations promotional allowances were $0.7 million and $0.8 million, respectively. The estimated cost of providing promotional allowances included in operating expenses for the nine months ended September 30, 2013 and 2012 totaled $7.0 million and $3.7 million, respectively.
Comprehensive Income	The Company had no other components of comprehensive income and, as such, comprehensive income is the same as net earnings as presented in the accompanying Condensed Consolidated Statements of Comprehensive Income.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
