Intangible Assets, Net (Excluding Goodwill) [Abstract]
Intangible Assets	Intangible Assets Intangible assets are reported in Other assets in our consolidated balance sheets. The carrying amount of indefinite-life intangible assets was not material for the years ended December 31, 2017 and December 31, 2016. During the third quarter of 2015, we performed an interim impairment evaluation of Pullmantur's trademarks and trade names using a discounted cash flow model and the relief-from-royalty method to compare the fair value of these indefinite-lived intangible assets to its carrying value. We used a discount rate comparable to the rate used in valuing the Pullmantur reporting unit in our goodwill impairment test. Based on our cash flow projections, we determined that the fair value of Pullmantur’s trademarks and trade names no longer exceeded their carrying value. Accordingly, we recognized an impairment charge of approximately $174.3 million to write down trademarks and trade names to their fair value. The charge reflected the full carrying amount of the trademark and trade names leaving Pullmantur with no intangible assets on its books. This impairment charge was recognized in earnings during the third quarter of 2015 and is reported within Impairment of Pullmantur related assets within our consolidated statements of comprehensive income (loss). Finite-life intangible assets had a gross carrying amount and accumulated amortization amount of $11.6 million and $3.7 million, respectively, as of December 31, 2017, consisting of operating licenses to operate in the Galapagos Islands. As of December 31, 2017, the remaining weighted average remaining life of these licenses were approximately 26.6 years. Amortization expense for finite-life intangible assets was immaterial to our consolidated financial statements.
