Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities Under the applicable accounting guidance for the consolidation of variable interest entities, we analyze our variable interests, including loans, guarantees, and equity investments, to determine if an entity in which we have a variable interest is a variable interest entity. Our analysis includes both quantitative and qualitative reviews. We base our quantitative analysis on the forecasted cash flows of the entity, and our qualitative analysis on our review of the design of the entity, its organizational structure including decision-making ability, and relevant financial agreements. We also use our qualitative analysis to determine if we must consolidate a variable interest entity as its primary beneficiary. In the 2013 second quarter, we purchased a $65 million mandatorily redeemable preferred equity ownership interest in an entity that owns three hotels, which we also manage. Please see Footnote No. 5, "Fair Value of Financial Instruments" for further information on the purchase and Footnote No. 11, "Contingencies" for information on the commitment we entered into as part of this transaction. Based on qualitative and quantitative analyses, we concluded that the entity in which we invested is a variable interest entity because it is capitalized primarily with debt. We did not consolidate the entity because we do not have the power to direct the activities that most significantly impact the entity's economic performance. Inclusive of our contingent future funding commitment, our maximum exposure to loss at the end of the 2013 second quarter is $76 million. In conjunction with the transaction with CTF that we describe more fully in our Annual Report on Form 10-K for 2007 in Footnote No. 8, “Acquisitions and Dispositions,” under the caption “2005 Acquisitions,” we manage hotels on behalf of tenant entities that are 100 percent owned by CTF, which lease the hotels from third-party owners. Due to certain provisions in the management agreements, we account for these contracts as operating leases. At June 30, 2013, we managed four hotels on behalf of three tenant entities. The entities have minimal equity and minimal assets, consisting of hotel working capital and furniture, fixtures, and equipment. As part of the 2005 transaction, CTF placed money in a trust account to cover cash flow shortfalls and to meet rent payments. In turn, we released CTF from its guarantees fully for two of these properties and partially for the other two properties. The trust account was fully depleted prior to year-end 2011. The tenant entities are variable interest entities because the holder of the equity investment at risk, CTF, lacks the ability through voting rights to make key decisions about the entities’ activities that have a significant effect on the success of the entities. We do not consolidate the entities because we do not have the power to direct the activities that most significantly impact the entities' economic performance. We are liable for rent payments for two of the four hotels if there are cash flow shortfalls. Future minimum lease payments through the end of the lease term for these hotels totaled approximately $8 million at the end of the 2013 second quarter. In addition, as of the end of the 2013 second quarter we are liable for rent payments of up to an aggregate cap of $5 million for the two other hotels if there are cash flow shortfalls. Our maximum exposure to loss is limited to the rent payments and certain other tenant obligations under the lease, for which we are secondarily liable.

Variable Interest Entities

Under the applicable accounting guidance for the consolidation of variable interest entities, we analyze our variable interests, including loans, guarantees, and equity investments, to determine if an entity in which we have a variable interest is a variable interest entity. Our analysis includes both quantitative and qualitative reviews. We base our quantitative analysis on the forecasted cash flows of the entity, and our qualitative analysis on our review of the design of the entity, its organizational structure including decision-making ability, and relevant financial agreements. We also use our qualitative analysis to determine if we must consolidate a variable interest entity as its primary beneficiary.
