YC is a lovely experience, I’m sure you will enjoy it.
Because of the amazing YC public areas we hardly spend any time in our cabin so nab a YC inside when we can, not always possible as they go fast.
Just for information the insides are small and little short on space for storage so we usually take some magnets for extra hanging space and lightweight collapsible boxes to store things like shoes. There is a useful space under the two chairs that takes a 10 by 10 by 10 box which you hide all sorts of bits and bobs in (if the sizing is the same on your ship, we have only been on Virtuosa and Euribea). Packing cubes are handy as well for the high top shelf.
As others have said, you will get hooked on the YC.
