Hi everyone! I'm starting a packing list for our Rhine River cruise and was just wondering what most guests wear to dinner? I am planning on bringing dresses and flats for myself, but I'm curious if we need to pack pants/dress shorts and polos for DH and DS16? (DH will always wear polos, but DS16, not so much . . . ) I'm used to things being quite casual in the DCL MDRs, but thought the river cruise dining rooms might expect an elevated dress code? Thank you for your thoughts!
