Exhibit 5.1 [LETTERHEAD OF LATHAM & WATKINS] June 15, 1998 Host Marriott Corporation 10400 Fernwood Road Bethesda, Maryland 20817-1109 Re: $2,500,000,000 Aggregate Offering Price of Securities of Host Marriott Corporation ------------------------------------------ Ladies and Gentlemen: In connection with the registration statement on Form S-3 of Host Marriott Corporation and the Co-Registrants (as defined below), as amended through the date hereof, (the "Registration Statement") filed on April 22, 1998 with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), you have requested our opinion with respect to the matters set forth below. You have provided us with a draft prospectus (the "Prospectus") which is a part of the Registration Statement. The Prospectus provides that it will be supplemented in the future by one or more supplements (each a "Prospectus Supplement"). The Prospectus as supplemented by various Prospectus Supplements will provide for the issuance and sale by Host Marriott Corporation, a Delaware corporation (the "Company"), of up to $2,500,000,000 aggregate offering price of: (i) debt securities of the Company consisting of debentures, notes or other evidences of indebtedness (the "Debt Securities"); (ii) shares of common stock of the Company, par value $1.00 per share (the "Common Stock"); (iii) shares of preferred stock of the Company, without par value (the "Preferred Stock"); (iv) shares of Preferred Stock represented by depositary shares (the "Depositary Shares"); (v) warrants to purchase Debt Securities, Common Stock, Preferred Stock or Depositary Shares (the "Warrants"); and (vi) subscription rights evidencing the right to purchase Debt Securities, Common Stock, Preferred Stock, Depositary Shares or Warrants (the "Subscription Rights"). In addition, Debt Securities may be issued, directly or through agents, dealers or underwriters designated from time to time, by one or more June 15, 1998 Page 2 of the Company's direct or indirect wholly owned subsidiaries which are co- registrants on the Registration Statement (each such subsidiary, a "Co- Registrant," and collectively, the "Co-Registrants"). The Registration Statement provides that Debt Securities may be convertible into shares of Common Stock, Preferred Stock or Depositary Shares, and that shares of Preferred Stock may be convertible into shares of Common Stock or Debt Securities. The Registration Statement provides that the Company's payment obligations under any series of Debt Securities may be guaranteed by certain of the Co-Registrants and the Registration Statement provides that the payment obligation of any Co-Registrant issuing any series of Debt Securities will be guaranteed by the Company and may be guaranteed by one or more of the Co-Registrants (each entity providing such guarantee, a "Guarantor" and collectively, the "Guarantors"). The Debt Securities, the Common Stock, the Preferred Stock, the Depositary Shares, the Warrants and the Subscription Rights are referred to herein as the "Offered Securities". The Debt Securities will be issued pursuant to one or more indentures in the form filed as an exhibit to the Registration Statement, as amended or supplemented from time to time (each, an "Indenture") between the Company or any one of the Co-Registrants, as the case may be, as obligor, and a trustee chosen by the Company and qualified to act as such under the Trust Indenture Act of 1939, as amended (each, a "Trustee"). The Depositary Shares will be issued under one or more deposit agreements (each, a "Deposit Agreement"), by and among the Company and a financial institution identified therein as the depositary (each, a "Depositary"). The Warrants will be issued under one or more warrant agreements (each, a "Warrant Agreement"), by and among the Company and a financial institution identified therein as warrant agent (each, a "Warrant Agent"). For purposes of this opinion, we have assumed that all proceedings taken and proposed to be taken by the Company in connection with the authorization and issuance of the Offered Securities and all the proceedings taken and proposed to be taken by such Co-Registrant in connection with the authorization and issuance of Debt Securities will be timely and properly completed, in accordance with all requirements of applicable Delaware and New York laws, in the manner presently proposed. We have made such legal and factual examinations and inquiries, including an examination of originals and copies certified or otherwise identified to our satisfaction, of all such documents, corporate records and instruments of the Company and the Co-Registrants as we have deemed necessary or appropriate for purposes of this opinion. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as copies. We have been furnished with, and with your consent have exclusively relied upon, certificates of officers of the Company and the Co-Registrants with respect to certain factual matters. In addition, we have obtained and relied upon such certificates and assurances from public officials as we have deemed necessary.
