The world’s largest cruise ship is set to begin its maiden voyage on Saturday.
Royal Caribbean’s Icon of the Seas will set sail from Miami in Florida with a capacity for up to 7,600 passengers and 2,350 crew members.
The ship runs nearly 1,200ft (365m) from bow to stern and is divided into eight neighbourhoods across 20 decks.
The vessel features six waterslides, seven swimming pools, an ice skating rink, a theatre and more than 40 restaurants, bars and lounges.
It will leave south Florida for its first seven-day island-hopping voyage in the tropics.
Icon of the Seas was officially christened on Tuesday with the help of football legend Lionel Messi and his Inter Miami teammates.
The ship is powered by six dual-fuel engines, which can be powered by liquefied natural gas (LNG), a fuel alternative the Cruise Lines International Association says reduces sulfur and greenhouse gas emissions.
However, environmental groups have raised concerns LNG-powered ships increase harmful methane emissions.
“It’s a step in the wrong direction,” Bryan Comer, director of the Marine Program at the International Council on Clean Transportation (ICCT), told Reuters.
“We would estimate that using LNG as a marine fuel emits over 120% more life-cycle greenhouse gas emissions than marine gas oil.”
