'HARMONY' MAY BE WORLD'S BIGGEST

Harmony of the Seas (Royal Caribbean)

While we are on the subject of size, Royal Caribbean may up the ante with its third Oasis-class ship, Harmony of the Seas. According to reports, it will surpass its sister ships and claim the largest cruise ship title when she launches in 2016.  Among other things, it will feature new multi-story water slides. The "WOW" keeps coming from Royal.
