                     REGISTRATION STATEMENT ON FORM S-3 ASR
                     --------------------------------------

Ladies and Gentlemen:

         In  connection with the  Registration  Statement  on Form S-3 ASR (the
"Registration  Statement") of Carnival Corporation (the "Company") and Carnival
plc ("Carnival  plc") filed today with the  Securities and Exchange  Commission
under the  Securities  Act of 1933,  as amended (the "Act"),  and the rules and
regulations  thereunder (the "Rules"), you have asked us to furnish our opinion
as to the legality of the securities  being  registered  under the Registration
Statement. 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" and,
collectively  with the Debt  Securities,  the  "Securities"),  (iii)  shares of
Preferred Stock (including shares issued upon conversion of Debt Securities) of
the Company,  par value $.01 per share (the "Preferred Stock"),  (iv) shares of
the Common Stock  (including  shares to be issued upon  conversion  of the Debt
Securities  or the  Preferred  Stock) of the Company,  par value $.01 per share
(the  "Common  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, and (vi) the guarantee by Carnival plc of the Debt
Securities  pursuant to the Carnival plc Deed of Guarantee  between the Company
and Carnival plc,  dated as of April 17, 2003.  The  Securities,  the Preferred
Stock,  the  Common  Stock,  the  Trust  Shares  and the  guarantee  are  being
registered  for  offering  and sale from time to time as  provided  by Rule 415
under the Act.





         The Senior Debt Securities are to be issued under an Indenture,  dated
as of April 25, 2001, between the Company and U.S. Bank,  National  Association
("U.S. Bank"), as Trustee (the "Senior Debt Indenture").  The Subordinated Debt
Securities  are to be issued  under an indenture to be entered into between the
Company  and the  trustee  under it (the  "Subordinated  Debt  Indenture"  and,
together with the Senior Debt Indenture, the "Indentures"). The Warrants are to
be issued under warrant agreements,  each between the Company, as issuer, and a
warrant agent (collectively, the "Warrant Agreements").

         In connection  with the  furnishing of this opinion,  we have examined
(i) originals or copies  certified or otherwise  identified to our satisfaction
of the Registration Statement (including the exhibits and amendments to it) and
(ii) the Senior Indenture and the form of the  Subordinated  Indenture filed as
exhibits to the Registration  Statement.  In addition,  we have made such other
examinations  of law and  fact as we  considered  necessary  in order to form a
basis for our  opinion.  We have also  relied upon the  certificates  of public
officials and the officers of the Company.

         In our  examination  of the  documents  referred  to  above,  we  have
assumed, without independent investigation,  the genuineness of all signatures,
the legal  capacity of all  individuals  who have executed any of the documents
reviewed by us, the authenticity of all documents submitted to us as originals,
the conformity to the originals of all documents  submitted to us as certified,
photostatic,  reproduced or conformed  copies of valid  existing  agreements or
other  documents,  the  authenticity  of all the latter  documents and that the
statements regarding matters of fact in the certificates,  records, agreements,
instruments and documents that we have examined are accurate and complete.

         In rendering the opinion set forth below, we have assumed that (i) the
Company has been duly organized and is validly  existing in good standing under
the laws of the  Republic  of Panama,  (ii) the Company has the legal power and
authority to enter into and perform its obligations  under the Indentures,  the
Warrant  Agreements  and the  Securities,  (iii) the  execution,  delivery  and
performance by the Company of the  Indentures,  the Warrant  Agreements and the
Securities  will not  conflict  with or violate  the  charter or by-laws of the
Company,  the laws of Panama or the terms of any  agreement  or  instrument  to
which the Company is  subject,  (iv) the Senior  Debt  Indenture  has been duly
authorized,  executed and delivered by the parties to it, (v) the  Subordinated
Debt Indenture shall have been duly  authorized,  executed and delivered by the
parties to it in substantially the form filed as an exhibit to the Registration
Statement,  (vi) the Senior Debt  Indenture  does,  and the  Subordinated  Debt
Indenture, when so executed and delivered,  will, represent a valid and binding
obligation of the  appropriate  trustee under the laws of its  jurisdiction  of
incorporation  and the State of New York and of the  Company  under the laws of
the Republic of Panama,  (vii) the Warrant  Agreements will be duly authorized,
executed and  delivered by the parties to it, and (ix) the Warrant  Agreements,
when so executed and delivered,  will represent a valid and binding  obligation
of the  appropriate  Warrant  Agent  under  the  laws  of its  jurisdiction  of
incorporation  and the State of New York and of the  Company  under the laws of
the Republic of Panama.

         We have also assumed,  with respect to the  Securities of a particular
series or issuance  offered (the "Offered  Securities"),  that (i) the terms of
issue and sale of the Offered  Securities  shall have been duly  established in
accordance with the appropriate Indenture or Warrant Agreement, as the case may
be, (ii) the Offered  Securities  shall have been duly  authorized,  issued and
delivered  by the  Company  and duly  authenticated  by the  Trustee or Warrant
Agent,  as the case may be, all in accordance with the terms of the appropriate
Indenture or Warrant Agreement,  as the case may be, and against payment by the
purchasers at the agreed  consideration and (iii) the Offered Securities,  when
so issued, authenticated,  delivered and sold, will represent valid and binding
obligations  of the  Company  under the laws of the  Republic  of Panama.  With
regard to such  assumptions,  we refer you to the  opinion of Taipa,  Linares y
Alfaro,  Panamanian  counsel  to  the  Company,  filed  as  Exhibit  5.2 to the
Registration Statement.




         Based on the above, and subject to the stated assumptions,  exceptions
and qualifications,  we are of the opinion that, when issued, authenticated and
delivered,  the Offered Securities will be legal, valid and binding obligations
of the Company under the laws of the State of New York enforceable  against the
Company in accordance with their respective terms, except as enforceability may
be limited by (a) bankruptcy,  insolvency,  fraudulent  conveyance or transfer,
reorganization,  moratorium and other similar laws affecting  creditors' rights
generally,  (b) subject to general  principles of equity (regardless of whether
enforcement  is  considered  in a  proceeding  in  equity  or at  law)  and (c)
requirements  that a claim with respect to any Offered  Securities  denominated
other than in United States  dollars (or a judgment  denominated  other than in
United States  dollars in respect of the claim) be converted into United States
dollars at a rate of exchange  prevailing  on a date  determined  by applicable
law.

         The opinion expressed above is limited to the laws of the State of New
York and the  federal  laws of the United  States of  America.  Our  opinion is
rendered only with respect to the laws, and the rules,  regulations  and orders
under those laws, that are currently in effect.

         We hereby  consent  to the use of this  opinion  as an  exhibit to the
Registration  Statement  and to the use of our name  under the  heading  "Legal
Matters" contained in the prospectus included in the Registration Statement. In
giving this  consent,  we do not thereby admit that we come within the category
of persons whose consent is required by the Act or the Rules.


                                            Very truly yours,


                             /s/ PAUL, WEISS, RIFKIND, WHARTON & GARRISON LLP
