Accounting Policies [Abstract]
Basis of Accounting	Basis for Preparation of Consolidated Financial Statements The unaudited consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Estimates are required for the preparation of financial statements in accordance with these principles. Actual results could differ from these estimates. See Note 2. Summary of Significant Accounting Policies in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2013 for a discussion of our significant accounting policies. All significant intercompany accounts and transactions are eliminated in consolidation. We consolidate entities over which we have control, usually evidenced by a direct ownership interest of greater than 50%, and variable interest entities where we are determined to be the primary beneficiary. See Note 5. Goodwill and Other Assets for further information regarding our variable interest entities. For affiliates we do not control but over which we have significant influence on financial and operating policies, usually evidenced by a direct ownership interest from 20% to 50%, the investment is accounted for using the equity method. We consolidate the operating results of Pullmantur and CDF Croisières de France on a two-month lag to allow for more timely preparation of our consolidated financial statements. Consistent with the two-month lag, the sale of the Pullmantur non-core businesses which closed on March 31, 2014, will be reported in our consolidated financial statements in our second quarter of 2014. For information on the sale of the Pullmantur non-core businesses, see Note 10. Restructuring Charges. No material events or other transactions affecting Pullmantur or CDF Croisières de France have occurred during the two-month lag period of February and March 2014 that would require further disclosure or adjustment to our consolidated financial statements as of and for the quarter ended March 31, 2014. We believe the accompanying unaudited consolidated financial statements contain all normal recurring accruals necessary for a fair presentation. Our revenues are seasonal and results for interim periods are not necessarily indicative of results for the entire year.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2014, amended guidance was issued regarding the accounting for service concession arrangements. The new guidance defines a service concession as an arrangement between a public-sector entity grantor and an operating entity under which the operating entity operates and maintains the grantor’s infrastructure for a specified period of time and in return receives payments from the grantor and or third party user for use of the infrastructure. The guidance prohibits the operating entity from accounting for a service concession arrangement as a lease and from recording the infrastructure used in the arrangement within property plant and equipment. This guidance must be applied using a modified retrospective approach and will be effective for our interim and annual reporting periods beginning after December 15, 2014. Early adoption is permitted. We are currently evaluating the impact, if any, of this newly issued guidance, the implementation of which is not expected to be material to our consolidated financial statements.
Reclassifications	Reclassifications For the three months ended March 31, 2013, $8.5 million has been reclassified in the consolidated statements of cash flows from other, net to (gain) loss on derivative instruments not designated as hedges within net cash flows provided by operating activities in order to conform to the current year presentation.
Other	Other Revenues and expenses include port costs that vary with guest head counts. The amounts of such port costs included in passenger ticket revenues on a gross basis were $124.1 million and $115.7 million for the first quarters of 2014 and 2013, respectively.
