It looks like Disney is coming in with all guns blazing. I hope they are successful where so many other cruise lines have failed in Asia. Norwegian Cruise Line, Royal Caribbean, Costa, and Princess all built mega-ships specifically designed for the region and all but one ship from Royal Caribbean (Spectrum of the Seas) failed and were quickly withdrawn and sent to other areas shortly after debuting.
The industry in Singapore is certainly much more stable than China, but it will definitely be a challenge filling such a large ship that does not have a casino. I hope I'm wrong.
