Cruised the Grandeur in March, '04. Most of the men (75%) had on suits rather than tuxes at the first dinner seating. I don't think if you wore a dark (navy or black) that you would feel out of place at all.
We cruised the Grandeur in April and most of us gentlemen wore dark suits. However, if you already own a tux and prefer it over a suit, then I say you should wear whatever you prefer. Enjoy your cruise!
whatever your wife or girl friend tells you to wear to make her look better (smile) doesn't matter, I agree with the above poster, if you own a tux (and don't get a whole lot of use out of it) and won't take up extra space in your bag, carry if, if not a nice dark suit will be just fine
lol, i am actually the wife! Me wants to wear his suit (thinks it's absurd to spend $100 to rent an outfit) and so I'm trying to find out if I push the tux issue i will find that he'd have been with the majority in his suit.
