Ladies and Gentlemen:

We have acted as special counsel in the State of Arizona for Best Western International, Inc., an Arizona corporation (the “Company”), in connection with the registration by the Company of 55,000,000 shares of its Common Stock, without par value (the “Common Stock”) pursuant to a Registration Statement on Form S-1 (Registration No. 333-_______), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”) (such Registration Statement, as amended or supplemented, is hereinafter referred to as the “Registration Statement”). The shares of Common Stock covered by the Registration Statement consist of shares of Common Stock to be issued in connection with the Company’s proposed merger with Best Western Merger Sub, Inc., with the Company surviving as an Arizona for-profit corporation (the “Merger”), and shares of Common Stock which may be issued by the Company after the effective date of the Merger as specified in the Registration Statement. The shares of Common Stock that are issued in accordance with the Merger are referred to herein as the “Conversion Shares.” The shares of Common Stock that may be issued by the Company after the effective date of the Merger are referred to herein as the “Post-Conversion Shares.”

In our capacity as special counsel to the Company, 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 rendering this opinion, including, without limitation, (i) the Plan of Merger, a form of which has been filed as Exhibit 2.1 to the Registration Statement; (ii) a form of the Statement of Merger to be filed with the Arizona Corporation Commission pursuant to the Plan of Merger; (iii) the Amended and Restated Articles of Incorporation of the Company, a form of which has been filed as Exhibit 3.3 to the Registration Statement; (iv) the Amended and Restated Bylaws of the Company, a form of which was filed as Exhibit 3.4 to the Registration Statement; (v) minutes and records of the corporate proceedings of the Company with respect to, among other things, the approval of the Merger and the issuance of the Conversion Shares and the Post-Conversion Shares; and (vi) the Registration Statement.
