Can anyone help me? I know Sunday & Thursday are the formal nights, but which are the casual & semi-formal. I think I read that Saturday night is casual, in case some luggage isn't delivered by dinner. We will be celebrating our 25th anniversary during the week & I want to dress up a little on that night, but not seem too overdressed if it's a casual night. I want to have enough comfortable, casual clothes & not too many semi-formal outfits. Maybe someone can check their old Carnival Capers & fill me in. Thanks for any help.
