Re:
Legality of Securities to be Registered Under Registration Statement on Form S-11

Ladies and Gentlemen:

        We have acted as counsel for DiamondRock Hospitality Company, a Maryland corporation (the "Company"), in connection with the preparation and filing with the Securities and Exchange Commission (the "Commission") of (i) a Registration Statement on Form S-11, Registration No. 333-132266, as amended (the "Initial Registration Statement"), and (ii) a second Registration Statement on Form S-11 to be filed pursuant to Rule 462(b) promulgated under the Securities Act of 1933, as amended (the "462(b) Registration Statement," and together with the Initial Registration Statement, the "Registration Statement"). This opinion is being rendered to you in connection with the filing of the 462(b) Registration Statement, pursuant to which the Company is registering 3,220,000 of its shares (the "Shares") of common stock $.01 par value per share.

        We have reviewed such documents and made such examination of law as we have deemed appropriate to give the opinions expressed below. We have relied, without independent verification, on certificates of public officials and, as to matters of fact material to the opinions set forth below, on certificates of officers of the Company.

        The opinion expressed below is limited to the Maryland General Corporation Law (which includes applicable provisions of the Maryland Constitution and reported judicial decisions interpreting the Maryland General Corporation Law and the Maryland Constitution).

        Based on the foregoing, we are of the opinion that the Shares have been duly authorized and, upon issuance and delivery against payment therefor in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and non-assessable.

        We hereby consent to the inclusion of this opinion as Exhibit 5.1 to the Registration Statement and to the references to our firm under the caption "Legal Matters" in the Registration Statement. In giving our consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.

    Sincerely,

Exhibit 8.1

As of March 30, 2006

DiamondRock Hospitality Company
6903 Rockledge Drive, Suite 800
Bethesda, MD 20817

Ladies and Gentlemen:

        We have acted as counsel for DiamondRock Hospitality Company, a Maryland corporation (the "Company"), in connection with a registration (the "Registration") of shares of common stock of the Company, par value $0.01 per share, as described in the registration statement on Form S-11 filed with the Securities and Exchange Commission (the "SEC") under the Securities Act of 1933, as amended (the "Securities Act"), on March 30, 2006 (the "Registration Statement"). This opinion letter addresses the Company's qualification as a real estate investment trust (a "REIT") under the Internal Revenue Code of 1986, as amended (the "Code"), and the accuracy of certain matters discussed in the Registration Statement under the heading "Federal Income Tax Considerations."

        In rendering the following opinions, we have reviewed and relied upon the Articles of Amendment and Restatement of Articles of Incorporation and Bylaws of the Company dated as of June 25, 2004, the Limited Partnership Agreement of DiamondRock Hospitality Limited Partnership (the "Partnership Agreement"), a Delaware limited partnership (the "Operating Partnership"), dated as of June 4, 2004 and as in effect as of the date hereof, and such other records, certificates, and documents as we have deemed necessary or appropriate for purposes of rendering the opinions set forth herein. For purposes of this opinion letter, we have assumed (i) the genuineness of all signatures on documents we have examined, (ii) the authenticity of all documents submitted to us as originals, (iii) the conformity to the original documents of all documents submitted to us as copies, (iv) the conformity, to the extent relevant to our opinions, of final documents to all documents submitted to us as drafts, (v) the authority and capacity of the individual or individuals who executed any such documents on behalf of any person, and (vi) the accuracy and completeness of all records made available to us.

        We also have reviewed and relied upon the representations, as to factual matters, and covenants of the Company and the Operating Partnership contained in a letter that the Company provided to us in connection with the preparation of this opinion letter (the "REIT Certificate"), and that we have discussed with the Company's representative, regarding the organization and operations of the Company and the Operating Partnership and other matters affecting the Company's ability to qualify as a REIT. For purposes of this opinion letter, we assume that each such representation and covenant has been, is and will be true, correct and complete, that the Company, the Operating Partnership and any subsidiaries have been, are and will be owned and operated in accordance with the REIT Certificate and that all representations that speak to the best of the belief and/or knowledge of any person(s) or party(ies), or are subject to similar qualification, have been, are and will continue to be true, correct and complete as if made without such qualification. To the extent such representations and covenants speak to the intended ownership or operations of the Company or the Operating Partnership, we assume that each of the Company and the Operating Partnership will in fact be owned and operated in accordance with such stated intent.

        Based upon the foregoing and subject to the limitations set forth herein, we are of the opinion that:

1



* * * * *

        We express no opinion other than the opinions expressly set forth herein. Our opinions are not binding on the Internal Revenue Service. The Internal Revenue Service may disagree with and challenge our conclusions, and a court could sustain such a challenge. Our opinions are based upon the Code, the Income Tax Regulations and Procedure and Administration Regulations promulgated thereunder and existing administrative and judicial interpretations thereof, all as in effect as of the date of this opinion letter. Changes in applicable law could cause the federal income tax treatment of the Company to differ materially and adversely from the treatment described above and render the tax discussion in the Registration Statement incorrect or incomplete.

        We are rendering this opinion letter to you in connection with the Registration and this opinion letter may not be relied upon by any other person or for any other purpose without our prior written consent. This opinion speaks only as of the date hereof, and we undertake no obligation to update this opinion or to notify any person of any changes in facts, circumstances or applicable law (including without limitation any discovery of any facts that are inconsistent with the REIT Certificate).


 

 

 

    Very truly yours,
    /s/ Goodwin Procter LLP
