Its pretty hard to paint the entire ship while it is still in service.
I am hoping for the same thing. It wouldn't be too difficult to rearrange and put the piano bar over where the library is currently. Just like Panorama and Horizon.
They usually keep things quiet until it is closer to the end of dry dock, that way if something happens, and something doesn't get added, people can't whine that they booked for only that reason.
Where would you put it?
