                            RESPONSE TO P&O PRINCESS


Carnival notes the announcement made earlier today by P&O Princess that its
southern European Joint Venture Agreement with Royal Caribbean Cruises
terminated on 1 January 2003 at no cost to P&O Princess.

Accordingly, the pre-condition to Carnival's proposal of 24 October 2002
relating to the termination of the Joint Venture Agreement has now been
satisfied.

Carnival looks forward to the final pre-condition to its proposal being
satisfied through the signing of the Implementation Agreement and recommendation
of the Carnival DLC by P&O Princess no later than 10 January 2003.

A further announcement will be made in due course.

CAUTIONARY NOTE CONCERNING FACTORS THAT MAY AFFECT FUTURE RESULTS

Certain statements in this announcement constitute "forward-looking statements"
within the meaning of the US Private Securities Litigation Reform Act of 1995.
Carnival Corporation has tried, wherever possible, to identify such statements
by using words such as "anticipate", "assume", "believe", "expect", "forecast",
"future", "intend", "plan" and words and terms of similar substance in
connection with any discussion of future operating or financial performance.
These forward-looking statements, including those which may impact the
forecasting of Carnival's net revenue yields, booking levels, pricing, occupancy
or business prospects, involve known and unknown risks, uncertainties and other
factors, which may cause Carnival's actual results, performances or achievements
to be materially different from any future results, performances or achievements
expressed or implied by such forward-looking statements. Such factors include,
among others, the following: general economic and business conditions which may
impact levels of disposable income of consumers and the net revenue yields for
Carnival's cruise products; consumer demand for cruises and other vacation
options; other vacation industry competition; effects on consumer demand of
armed conflicts, political instability, terrorism, adverse media publicity and
the availability of air service; shifts in consumer booking patterns; increases
in vacation industry capacity, including cruise capacity; continued availability
of attractive port destinations; changes in tax laws and regulations; changes
and disruptions in equity, financial and insurance markets; Carnival's financial
and contractual counterparties' ability to perform; Carnival's ability to
implement its brand strategy, Carnival's ability to implement its shipbuilding
program and to continue to expand its business worldwide; Carnival's ability to
attract and retain shipboard crew; changes in foreign currency and interest
rates and increases in security, food, fuel, and insurance costs ; delivery of
new ships on schedule and at the contracted prices; weather patterns and natural
disasters; unscheduled ship repairs and drydocking; incidents involving cruise
ships; impact of pending or threatened litigation; Carnival's ability to
successfully implement cost improvement plans; the continuing financial
viability and/or consolidation of Carnival's travel agent distribution system;
Carnival's ability to successfully integrate business acquisitions and changes
in laws and regulations.

These risks may not be exhaustive. Carnival operates in a continually changing
business environment, and new risks emerge from time to time. Carnival cannot
predict such risks nor can it assess the impact, if any, of such risks on its
business or the extent to which any risk, or combination of risks may cause
actual results to differ from those projected in any forward-looking statements.
Accordingly, forward-looking statements should not be relied upon as a
prediction of actual results. Carnival undertakes no obligation publicly to
update or revise any forward-looking statements, whether as a result of new
information, future events or otherwise.
