Todd, you definitely don't need to get a tux unless you want to for other reasons (the Oscars at some point in the future, maybe?!) You will see a 50-50 split, maybe even less for the tux. At any rate, neither of you has to worry. Todd looks great in his dark suit (as I can attest) and Jim looks great in his suit (from his avatar!) Besides, Ken never wears a tux on-board that I know of. (Of course, the only time I was with him was when tux was not required, but as I remember, Ngaire says he does not like them!) I say do what you want, but don't feel pressure! We will definitely not be with "world cruisers" on this cruise who like that kind of thing or just think it is expected on that kind of voyage.
