Because I have been doing alot of research on the Prima, which is the sister ship of the Viva. Not only that, with it only being 6 months old, not all the kinks and whatnot may be worked out. And if they still are having supply chain issues, which we don't know, they could push it back again. Only time will tell. Our party has just decided to wait until that ship is broken in some before sailing on it and we are switching to a different ship.
