Same experience we had on Thanksgiving. Thought it would be a cool to experience a holiday outside of the normal way we've done forever. We found ourselves missing the traditions of home. Probably won't ever sail Thanksgiving again nor try xmas.
I think a news year eve cruise could be fun, however.
Edit to add the dining room had "Thanksgiving" dinner....it was anything but. They tried, I don't know if it's not in their wheelhouse or mass preparing Turkey and trimmings is super difficult....but it wasn't good.
