This really is just a way for carnival corp to utilize excess (and currently unprofitable) tonnage in a way that makes sense. If it is a success, they *may* bring more ships over. In NY, it will compete with MSC (and the NYC market has a ton of italian-americans to draw from). My understanding is that this is going to be quite literally a Costa ship with a Carnival touch (crew, entertainment, etc). Very little drydocking is being done aside from the updated livery and some of the funship 2.0 stuff (https://www.cruisecritic.com/articles.cfm?ID=3389) link explains funship 2.0 stuff
