Re: Guarantees of the obligations owed under the $1,500,000,000 aggregate principal amount of 5.625% Senior Notes due 2021

Ladies and Gentlemen:

We have acted as counsel to Hilton Worldwide Finance, LLC, a Delaware limited liability company (the “Company”), and Hilton Worldwide Finance Corp., a Delaware corporation (together with the Company, the “Issuers”), and to the subsidiaries of the Company listed on Schedule I (the “Nevada Guarantors”), in connection with the Registration Statement on Form S-4 (the “Registration Statement”) filed by the Issuers and the Guarantors (as defined below) with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, relating to the issuance by the Issuers of up to $1,500,000,000 aggregate principal amount of 5.625% Senior Notes due 2021 (the “Exchange Securities”) and the issuance by the Guarantors of guarantees (the “Exchange Guarantees”) of the Issuers’ obligations with respect to the Exchange Securities. The Exchange Securities and the Exchange Guarantees will be issued under an indenture, dated as of October 4, 2013 (as amended by the first supplemental indenture, dated as of October 25, 2013, and the second supplemental indenture dated September 8, 2014, altogether, the “Indenture”), among the Issuers, the Nevada Guarantors, the other guarantors party thereto (together with the Nevada Guarantors, the “Guarantors”) and Wilmington Trust, National Association, as trustee (the “Trustee”). The Exchange Securities and the Exchange Guarantees will be offered by the Issuers and Guarantors in exchange for their outstanding 5.625% Senior Notes due 2021 and the guarantees thereof of the Guarantors.

We have examined the Registration Statement and the Indenture, which has been filed with the Commission as an exhibit to the Registration Statement. We also have examined the originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and have made such other investigations as we have deemed relevant and necessary in connection with the opinions hereinafter set forth. As to questions of fact material to this opinion, we have relied upon certificates or comparable documents of public officials and of officers and representatives of the Issuers and the Guarantors.
