When we boarded the Nova yesterday, I asked our butler and he said it was going to be a private ceremony. I did notice groups of professionally dressed people walking through the ship in the afternoon who I assume were invited for the ceremony. As guests, the only thing that we saw that I assume was related to this was 2 tugs put on an impressive water canon show we could enjoy on our balcony. It was fun to see and went for quite a while. Other than that, we did not know a thing until I saw pictures on Facebook.
