We are cruising on the Dream in January. 4 day Bahama's... What's the rule on Formal wear for dinner?? I know on the 7 day cruise there's 1 Formal dinner, but what about 4 day ones? I'm buying little Cindarella and Belle gowns for my daughters, I thought it'd be fun for me to get a similiar gown to doll up in for at least one of our dinner meals. I'm not so worried about my little guy as a suit, button down shirt and nice tie will probably suffice for him, but how formal can/should us girls go on a 4 night?
