The Genesis project underconstruction at Aker Yards for RCI has had her secrets revealed by the builder. The details were kept under wraps for a while now but RCI announced in the last few days these details. The details of the Central Park which is basically a RCI Royal Promanade without the roof complete with real grass, trees and foliage, flowers etc.
There is also a lifting bar to be put onboard. If anyone had any concerns about if Genesis will have the Royal Promanade, I believe she will but it will be located under the floor of the Central Park area.
