I think it is actually in the same step as a changing football-player from Club A to B.
All media are reporting it already - but the medical-check and final contract-signing is still missing... .
This ship is a really "mass-product" with relative small cabins designed for Asians. So for 1 or 2 or 3 week-cruises of high standard it is not the best, with ca. 9000 people much too full onboard for relaxing etc. . But for to stay only 1, 2 or 3 nights on a floating Disney World with "1000" slides, games, movies, playgrounds etc. it is a good solution.
It is similar as big hotels beside big entertainment-leisure-parks like f.ex. the "Europa Park in Rust".
They have many 1000 own hotel-rooms directly beside the park-entrance. So the people / families stay there only 1, 2, 3 nights for to use all things in the park - but not for a longer holiday-stay of weeks. And in the same way this ship is perfect as floating Disney-World offering also the Disney World experience for people in smaller and far away countries directly at her coast.
In January in Malaysia, in February in Vietnam, in march in Hongkong, in April in Seoul, in may in Japan, in June in Australia, in July in New Zealand, in August in Chile etc. . Stay in one country so long the people of this country full-booking the hotel-nights on the ship, and if the booking-numbers go down the ship goes further to the next country. If i would be the Disney World manager - i can not see any better solution than this ship ! Much more easier to get mass of people onboard the ship at her home-coast than to get all the people traveling expensive to Paris or Orlando.
