Except for the Rosario Strings and the Buenos Aires tango show, the others seemed a bit tired. Jody the piano guy was a disappointment as we normally like to sit and listen and sing along with the piano man.
The other area that could be improved was the lack of 24 hour food. The larger ships have a place where you can get some some savory and sweet snacks almost round-the-clock.
One thing they added for the lunches in the dining room was some hot buffet and dessert. This combined with the tutti salad bar made the lunchtime much more enjoyable. Whoever thought of that gets a gold star. Otherwise the repeating lunch menu got tired real quick.
