Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt In April 2015, we took delivery of Anthem of the Seas. To finance the purchase, we borrowed $742.1 million under a previously committed unsecured term loan which is 95% guaranteed by Euler Hermes Deutschland AG ("Hermes"), the official export credit agency of Germany. The loan amortizes semi-annually over 12 years and bears interest at LIBOR plus a margin of 1.30%, currently totaling 1.71%. In addition, during 2012, we entered into forward-starting interest rate swap agreements which effectively converted the floating rate available to us per the credit agreement to a fixed rate, including the applicable margin, of 3.86% effective April 2015 through the remaining term of the loan. See Note 9. Fair Value Measurements and Derivative Instruments for further information regarding these agreements.
