I am not sure why people criticise this cruise ship, we have been on Disney, Royal Carribean, Princess, Costa, MSC, NCL and Holland America and the ship compares favourably against all of these with the exception of Holland America which was our favourite. It is clean, well maintained, the crew are excellent, the entertainment was good, the food is pretty average but not imaginative.
It styles itself as a fun cruise and it is that, a lot of american teens and twenties on board make it a noisy but fun cruise (we are in out 60's) but not too annoying.
Jase the Cruise Director is excellent and the entertainment around the ship is good, particularly enjoyable is Gilbert in the Piano Bar who is brilliant.
Beautiful City we stayed in the French Quarter at Maison Dupuy which was really nice apart from a very strange shower.
Have been here before the shopping is a bit boring, so book a tour.
