It looks like they are doing some major structural modifications to the ship - a mid life refit.
They are going to add the extra quarter deck that the Triumph and Victory have. The aft lounge is gone, and replaced with balcony cabins. The main lounge will only be 2 decks instead of the current 3. The main floor where the stage is will be moved up one deck, and the old main floor will now have cabins in its place.
I am very interested in one of the 9 day European Cruises.
Names notwithstanding, is it not considered bad luck to rename a ship? I have heard of a few cases where ships were renamed, and then had something unlucky happen.
