The aft wraparound balconies on Spirit Class ships were Cat 11 suites before they changed the designation to Vista Suite (VS).
On Conquest class ships they still are Cat 9C balcony cabins.
I sailed on the Carnival Legend in 5266 and it was a Cat 11. These former Cat 11, suite cabins are now the "Vista Suites". I can see why they reclassified them since they already have the suite furnishings, jacuzzi tub and granite counters.
Regardless: Carnival can now charge more for those wonderful aft cabins.
