<P> In February 2014, Allure of the Seas entered dry dock at Grand Bahama island for seven days to replace a damaged gearbox in one of her Azipods . As the dry dock facility was not large enough to fully accommodate an Oasis - class ship, a unique solution had to be devised to allow the replacement, known as "Project Atlantis". During her time in dry dock, the crew used the downtime to make numerous repairs and refurbishments to the guest facilities, including the installation of new carpets . </P> <P> Allure of the Seas sailed year - round in the Caribbean region out of Port Everglades from its homeporting in 2010 through 2014 . She changed port to Barcelona and sailed the Mediterranean between May and October 2015, becoming the largest cruise ship and the first Oasis - class ship to spend a full season in that region . Afterward, she returned to Port Everglades . </P> <P> Allure of the Seas will change its home port in November 2018 to the Port of Miami, where Royal Caribbean will construct a new cruise terminal . She will be joined by the fourth Oasis - class vessel, MS Symphony of the Seas, and both will sail year - round from the port offering seven - night Western and Eastern Caribbean cruises . </P> <P> While the design length of Allure of the Seas is the same as that of her sister, 360 metres (1,181 ft), she is actually 362 metres (1,187 ft) long and is some 50 millimetres (2 in) longer than Oasis of the Seas . According to the shipyard, this is not intentional and such small differences in length may occur simply due to the temperature of the steel in a ship as big as this . The gross tonnage of Allure of the Seas is 225,282 and her displacement is equal to that of Oasis of the Seas, which is estimated to be around 100,000 metric tons, slightly less than that of an American Nimitz - class aircraft carrier . Her steel hull alone weighs roughly 54,000 tons . </P>

Where does the allure of the seas go
