You and your Husband will need at least one nice outfit for dinner, my husband had to wear a jacket, I a dress. The rest of the time he could wear t-shirt w/collar (like a golf shirt), I wore long pants with a nice blouse. Sweaters, under shirts and jackets, wool hats, gloves, warm socks when up on top of the deck, on land we wore sweater and jackets, carried umbrellas for just in case. We had a great time.
