         The prospectus dated July 3, 2003, as amended and supplemented by
prospectus supplement No. 1 dated July 21, 2003, prospectus supplement No. 2
dated August 8, 2003, prospectus supplement No. 3 dated August 25, 2003,
prospectus supplement No. 4 dated September 11, 2003 and prospectus supplement
No. 5 dated October 6, 2003 relating to the offer for resale of $889,000,000
aggregate principal amount at maturity of debentures and 20,896,657 shares of
our common stock issuable upon conversion of the debentures held by the selling
securityholders, plus an indeterminate number of shares as may become issuable
upon conversion of the debentures by reason of adjustment to the conversion
price and, upon each issuance of shares of Carnival Corporation common stock to
a person, including to a holder of debentures upon conversion of debentures, an

the table under the heading "Selling Securityholders" on page 74 with the
information in the following paragraph and table. We may further amend or

         We originally sold the debentures to the initial purchaser in a private
placement. The debentures were subsequently resold by the initial purchaser to
purchasers, including the selling securityholders listed below, in transactions
exempt from registration. The following table provides, as of October 31, 2003,
the principal amount at maturity of debentures held by such selling
securityholder, the number of shares of common stock beneficially owned by such
securityholder prior to its conversion of any debentures and the number of
shares of our common stock issuable upon conversion of the debentures. This
information has been obtained from the selling securityholders.
