Last month, we had one formal night in our 17 day cruise on the Navigator. Our bags were pushing the 50 pound limit so I chose to leave my tux at home. I asked three ship officers about the formal night and offered to eat in my cabin. They all said that I should eat in the Compass Rose and I would be fine in my blazer and tan pants with tie. It worked out fine; there were tuxes, suits and some people dressed as I was.
