Re:    Registration Statement on Form S-4

Ladies and Gentlemen:

We are issuing this opinion letter in our capacity as special counsel for Marriott Ownership Resorts, Inc., a Delaware corporation (the “Issuer”), each of the Delaware entities listed on Exhibit A hereto (the “Delaware Guarantors”) and each of the Florida, Hawaii and South Carolina entities listed on Exhibit B hereto (the “Other Guarantors” and, together with the Delaware Guarantors, the “Guarantors” and each a “Guarantor”). The Guarantors and the Issuer are collectively referred to herein as the “Registrants.” This opinion letter is being delivered in connection with the proposed registration by the Registrants of up to $350,000,000 aggregate principal amount of 4.750% Senior Notes due 2028 (the “Exchange Notes”), to be guaranteed by the Guarantors, pursuant to a Registration Statement on Form S-4 filed on or about the date hereof with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). Such Registration Statement, as amended or supplemented, is hereinafter referred to as the “Registration Statement.” The Exchange Notes are to be issued pursuant to an indenture, dated as of October 1, 2019, by and among the Issuer, the Guarantors party thereto, and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as amended by the Supplemental Indenture, dated December 31, 2019, by and among the Issuer, MVW Vacations, LLC and the Trustee and the Second Supplemental Indenture, dated February 26, 2020, by and among the Issuer, MVW Services Corporation, and the Trustee (together, the “Indenture”). The Indenture includes the guarantees by the Guarantors of the Exchange Notes (collectively, the “Guarantees”). The Exchange Notes are to be issued in exchange for the Issuer’s 4,750% Senior Notes due 2028 originally issued on October 1, 2019 in the aggregate principal amount of $350,000,000 (the “Original Notes”).

We have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary for the purposes of this opinion, including (i) certificates of incorporation, certificates of formation, bylaws, limited liability agreements, partnership agreements and other organizational documents, as applicable, of the Issuer and the Delaware Guarantors, (ii) resolutions or written consents of the board of directors, board of managers, manager, managing member, sole member or general

partner, as applicable, of the Issuer and the Delaware Guarantors with respect to the issuance of the Exchange Notes and the Guarantees, as applicable, (iii) the Indenture (including the Guarantees contained therein), (iv) the Registration Statement, (v) the Registration Rights Agreement, dated as of October 1, 2019, by and among the Issuer, the Guarantors party thereto, and J.P. Morgan Securities LLC, as representative of the initial purchasers of the Original Notes, and (vi) forms of the Exchange Notes and the Guarantees.

For purposes of this opinion, we have assumed the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity of the originals of all documents submitted to us as copies. We have also assumed the genuineness of the signatures of persons signing all documents in connection with which this opinion is rendered, the authority of such persons signing on behalf of the parties thereto, and the due authorization, execution and delivery of all documents by the parties thereto other than the Issuer and the Delaware Guarantors. As to any facts material to the opinions expressed herein that we have not independently established or verified, we have relied upon statements and representations of officers and other representatives of the Issuer and the Guarantors.

We have also assumed that the execution and delivery of the Indenture and the Exchange Notes and the performance by the Issuer and the Guarantors of their respective obligations thereunder do not and will not violate, conflict with or constitute a default under any agreement or instrument to which any Registrant is bound.

Our opinion expressed below is subject to the qualifications that we express no opinion as to the applicability of, compliance with, or effect of (i) any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar law affecting the enforcement of creditors’ rights generally, (ii) general principals of equity (regardless of whether enforcement is considered in a proceeding in equity or at law) and (iii) public policy considerations that may limit the rights of parties to obtain certain remedies.

Based upon and subject to the foregoing qualifications, assumptions and limitations and the further limitations set forth below, we are of the opinion that when (i) the Registration Statement becomes effective, (ii) the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and (iii) the Exchange Notes and the Guarantees have been duly executed and authenticated in accordance with the provisions of the Indenture and duly delivered to holders of the Original Notes in exchange for the Original Notes and the guarantees related thereto pursuant to the exchange offer described in the Registration Statement (assuming the due authorization and execution of the Guarantees by the Other Guarantors and the due delivery of the Guarantees by the Other Guarantors to holders of the Original Notes in exchange for the Original Notes and the guarantees related thereto), the Exchange Notes will be validly issued under the Indenture and will be binding obligations of the Issuer and the Guarantees will be validly issued under the Indenture and will be binding obligations of the Guarantors.
