I choose the Armonia for two reasons. The first was the stop in Cuba. The second because I've sailed the MSC Seaside numerous times and was so impressed with MSC at that point.
The Armonia was an older refurbished vessel and it was very clean and well laid out.
I enjoyed the smaller size but can only rate the café as average. They really needed more variety for those who dine there exclusively.
It was an excellent location and a very comfortable and well organized.
We rocked at a commercial port where cargo (mostly containers) were unloaded. There was NOTHING available to a passenger to enjoy without paying for an excursion. I often prefer to wander and explore near to the ship by walking.
