I've been known to slip extra hangers in my luggage in the past - but with the cost of checking bags and extra weight tariffs, I don't do that anymore. Since we arrived a day early on our last cruise, I was able to pick up extra hangers at a dollar store that was across the street from our hotel and I just left them in the closet. Hangers are always a problem in a ship's cabin . . it also helps to double hang - shirts over slacks and or skirts, etc.
