Re:   Registration Statement on Form S-3

Dear Sirs:

In connection with the above-captioned Registration Statement on Form S-3 (the “Registration Statement”) filed by Carnival Corporation, a corporation incorporated under the laws of the Republic of Panama (the “Company”), and Carnival plc, a public limited company incorporated under the laws of England and Wales (“Carnival plc”), with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the “Act”), and the rules and regulations promulgated thereunder, we have been requested to render our opinion as to the legality of the securities being registered thereunder. The Registration Statement relates to the registration under the Act of (i) the Company’s senior debt securities (“Senior Debt Securities”) and subordinated debt securities (“Subordinated Debt Securities” and, together with the Senior Debt Securities, the “Debt Securities”), consisting of notes, debentures and/or other evidences of indebtedness denominated in United States dollars or any other currency, (ii) the Company’s Warrants (the “Warrants”), (iii) shares of Common Stock (including shares to be issued upon conversion of the Debt Securities or the Preferred Stock (as defined below) of the Company, par value $.01 per share (the “Common Stock”), (iv) shares of Preferred Stock (including shares to be issued upon conversion of the Debt Securities) of the Company, par value $.01 per share (the “Preferred Stock”), (v) trust shares of beneficial interest in the P&O Princess Special Voting Trust (“Trust Shares”), a trust established under the laws of the Cayman Islands, which Trust Shares are paired with the shares of the Company’s Common Stock on a one-for-one basis which represent a beneficial interest in a special voting share of

Carnival plc (the “Voting Trust Deed”), (vi) contracts obligating holders to purchase from the Company and the Company to sell to the holders, a specified principal amount of Debt Securities, Common Stock, Trust Shares or Preferred Stock, government securities, or any of the other securities that the Company may sell under the Prospectus at a future date or dates (the “Purchase Contracts”), (vii) units comprised of one or more of the other securities that may be offered by the Company under the Prospectus, in any combination units ( “Units”), and (viii) guarantees by Carnival plc of the Company’s contractual monetary obligations under some or all of the Debt Securities pursuant to the Indentures (as defined below) (the “Guarantees”). The Debt Securities, Warrants, Common Stock, the Preferred Stock, the Purchase Contracts, the Units and the Guarantees, are hereinafter together referred to as the “Securities”. The Securities and the Trust Shares are being registered for offering and sale from time to time pursuant to Rule 415 under the Act.

The Senior Debt Securities and the related Guarantees are to be issued under an Indenture to be entered into between the Company, Carnival plc, as guarantor, and U.S. Bank National Association (“U.S. Bank”), as Trustee (the “Senior Indenture”). The Subordinated Debt Securities and the related Guarantees are to be issued under an indenture (the “Subordinated Indenture”) to be entered into between the Company, Carnival plc, as guarantor, and U.S. Bank, as trustee (the Subordinated Indenture together with the Senior Indenture, are hereinafter referred to as the “Indentures”). The Warrants are to be issued pursuant to either a warrant agreement relating to Warrants to purchase Debt Securities or a warrant agreement relating to the purchase of other types of Warrants, each between the Company, as issuer, and a bank or trust company, as warrant agent (collectively, the “Warrant Agreements”). The Purchase Contracts are to be issued pursuant to purchase contract agreements (the “Purchase Contract Agreements”) separately or as part of units consisting of a Purchase Contract and other securities or obligations issued by the Company or third parties, including United States treasury securities, securing the holders’ obligations to purchase the relevant securities under the Purchase Contracts. The Units are to be issued pursuant to unit agreements (the “Unit Agreements”) so that the holder of the Unit is also the holder of each security included in the Unit.

In this connection we have examined (i) originals, photocopies or conformed copies of the Registration Statement, including the exhibits and amendments thereto, (ii) the forms of the Indentures, including the Guarantees, and the Voting Trust Deed filed as exhibits to the Registration Statement, and (iii) records of certain of the Company’s corporate proceedings relating to, among other things, the proposed issuance and sale of the Securities. In addition, we have made such other examinations of law and fact as we considered necessary in order to form a basis for the opinion hereinafter expressed. In connection with such investigation, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as photocopies or conformed copies. We have relied as to matters of fact upon certificates of officers of the Company.
