                  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) 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"), and (vi) a guarantee by
Carnival plc of the Company's  contractual  monetary obligations under the some
or all 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 "Carnival
plc Guarantee"). The Preferred Stock, the Debt Securities, Warrants, and Common
Stock,  are  hereinafter   together  referred  to  as  the  "Securities".   The
Securities,  the  Trust  Shares  and  the  Carnival  plc  Guarantee  are  being
registered  for offering and sale from time to time  pursuant to 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  Indenture").  The Subordinated Debt Securities
are to be  issued  under an  indenture  (the  "Subordinated  Indenture")  to be
entered  between  the  Company  and a  trustee  to be named  in the  applicable
prospectus supplement (the "Subordinated  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  warrant  agent   (collectively,   the  "Warrant
Agreements").

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,  the Carnival plc Guarantee, 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.

In rendering  the opinion set forth below,  we have assumed that (i) the Senior
Indenture  has been duly  authorized  by the  parties  thereto  other  than the
Company,   and  has  been  executed  and  delivered  by  U.S.  Bank,  (ii)  the
Subordinated  Indenture  shall have been  executed and delivered by the parties
thereto other than the Company in substantially the form filed as an exhibit to
the  Registration   Statement,   (iii)  the  Senior  Indenture  does,  and  the
Subordinated 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, with respect to the
Senior  Indenture,  and the  applicable  jurisdiction  of governing  law of the
Subordinated  Indenture,  with respect to the  Subordinated  Indenture (iv) the
Warrant  Agreements  will be duly  authorized,  executed  and  delivered by the
parties thereto,  (v) the Warrant  Agreements,  when so executed and delivered,
will  represent a valid and binding  obligation of the  appropriate  thereunder
Warrant  Agent  under  the  laws  of  its  jurisdiction  of  incorporation  and
applicable  jurisdiction of governing law of such Warrant Agreements,  (vi) the
Carnival plc Guarantee is a valid and binding  obligation of Carnival plc under
the laws of its  jurisdiction  of  incorporation  and the Isle of Man, has been

duly  authorized  by all  necessary  corporate  action by Carnival plc and duly
executed and delivered by Carnival plc,  (vii) the Voting Trust Deed is a valid
and binding obligation of The Law Debenture Trust Corporation  (Cayman) Limited
under the laws of its jurisdiction of incorporation and the Cayman Islands, has
been duly  authorized  by all necessary  corporate  action by The Law Debenture
Trust  Corporation  (Cayman) Limited and duly executed and delivered by The Law
Debenture Trust  Corporation  (Cayman)  Limited.  We have also assumed that the
Securities,  except shares of Common Stock and Preferred Stock, of a particular
issuance offered will be duly executed,  issued,  authenticated  and delivered,
and sold as described in the Registration Statement.

Based on the foregoing, we are of the opinion that:

1.     The execution and delivery of the Indentures,  the Voting Trust Deed and
       Warrant  Agreements,   the  performance  of  the  Company's  obligations
       thereunder,  the  execution,  issuance  and  delivery of the Senior Debt
       Securities,  Subordinated Debt Securities, Trust Shares and Warrants, as
       applicable,  and the performance of the Company's obligations thereunder
       have been duly authorized by the Company.

2.     The  Indentures,  when duly executed and delivered,  and the Senior Debt
       Securities and Subordinated  Debt Securities,  as applicable,  when duly
       issued,  authenticated,  delivered and paid for, as  contemplated in the
       Registration   Statement  and  in  accordance  with  the  terms  of  the
       respective  Indenture,  will represent valid and binding  obligations of
       the Company,  enforceable  against the Company in accordance  with their
       respective terms,  except that such enforceability may be subject to (a)
       bankruptcy,    insolvency,   fraudulent   conveyance,    reorganization,
       moratorium or other similar laws affecting  creditors' rights generally,
       (b) general principles of equity (regardless of whether such enforcement
       is considered in a proceeding in equity or at law) and, (c) requirements
       that a claim with respect to any Debt Securities  denominated other than
       in United States dollars (or a judgment denominated other than in United
       States dollars in respect of such claim) be converted into United States
       dollars at a rate of exchange  prevailing on a date determined  pursuant
       to applicable law.

3.     The  Warrant  Agreements,  when  duly  executed  and  delivery,  and the
       Warrants  when duly issued,  authenticated,  delivered  and paid for, as
       contemplated  in the  Registration  Statement and in accordance with the
       terms of the respective  Warrant  Agreement,  will  represent  valid and
       binding  obligations of the Company,  enforceable against the Company in
       accordance with their respective terms,  except that such enforceability
       may be subject to (a)  bankruptcy,  insolvency,  fraudulent  conveyance,
       reorganization,  moratorium or other similar laws  affecting  creditors,
       rights  generally,  (b)  general  principles  of equity  (regardless  of

       whether such  enforcement  is considered in a proceeding in equity or at
       law) and,  (c)  requirements  that a claim with  respect to any Warrants
       denominated   other  than  in  United  States  dollars  (or  a  judgment
       denominated  other  than in United  States  dollars  in  respect of such
       claim) be  converted  into United  States  dollars at a rate of exchange
       prevailing on a date determined pursuant to applicable law.

4.     The shares of Common Stock are either duly  authorized,  validly issued,
       fully paid and  non-assessable  or, when issued and sold as contemplated
       in the  Registration  Statement and any prospectus  supplement  relating
       thereto,  against  payment of the  consideration  fixed  therefor by the
       Board of Directors or a committee thereof, and assuming that the Company
       at such time has a sufficient  number of authorized but unissued  shares
       of Common Stock remaining under its Articles of  Incorporation,  will be
       duly authorized, validly issued, fully paid and nonassessable.

5.     The shares of Preferred  Stock,  when issued and sold as contemplated in
       the Registration  Statement and any applicable prospectus supplement and
       the provisions of an applicable Certificate of Designation that has been
       duly adopted by the Board of Directors and duly filed in accordance with
       Panama law and against  payment of the  consideration  fixed therefor by
       the Board of  Directors  or a duly  authorized  committee  thereof,  and
       assuming  that the  Company  at such  time has a  sufficient  number  of
       authorized but unissued  shares of Preferred  Stock  remaining under its
       Articles  of  Incorporation,  will be  validly  issued,  fully  paid and
       nonassessable.

6.     The shares of Common Stock and Preferred  Stock issuable upon conversion
       of the Debt Securities will be duly authorized and reserved for issuance
       and will be validly issued,  fully paid and nonassessable,  assuming the
       execution, authentication,  issuance and delivery of the Debt Securities
       and  conversion of the Debt  Securities in accordance  with the terms of
       any  Indenture or any  supplement or officers'  certificate  thereto and
       assuming  that the  Company  at such  time has a  sufficient  number  of
       authorized  but  unissued  shares of Common  Stock and  Preferred  Stock
       remaining under its Articles of Incorporation.

7.     Neither  distributions  to the  holders  of shares  of  Common  Stock or
       Preferred  Stock nor the interest  paid on the Debt  Securities  will be
       subject to taxation under the laws of Panama. Also, the Company's income
       will not be subject to significant taxation under the laws of Panama, as
       long as the  Company's  income is produced  outside the territory of the
       Republic of Panama.

8.     The Company is duly  incorporated  and validly existing as a corporation
       in good standing under the laws of the Republic of Panama.
