We chose this cruise for the itinerary and because we wanted to try a European line after having cruised over 25 times on the mainstream American lines. Here goes:
First: this itinerary allows passengers to start and end the cruise in any of the 7 ports. So the embarkation process was quick since we didn't have to deal with all 4200 people getting on at the same time.
Second: the ship is absolutely gorgeous! Real marble, beautiful lighting, every nook and cranny was more attractive than the next!
