You don't have to wear a tux to fit in. My husband has worn a nice suit the last few cruises we've been on and he's looked just fine. As a matter of fact I think more men are opting for suits than tuxes...at least that's what I've noticed. But if you do opt for the tux I don't think you'll be the only "penquin" out there! You will still find some men wearing the tux.
