Which RCI Ship offers Zumba?

[cidymom]

I was on Navigator recently and they offered Zumba on sea days. Does anyone know if other RCI ships offer Zumba as well? I've been on the Allure and Anthem and they didn't have it. Thanks in advance for your help.

Serenade does every time I sail on her. But have heard some ships don't if no Zumba instructor on board
