I saw the earlier discussion on formal (or informal) wear on the ship. What are the expected dress codes for evening? We have our first SS cruise booked (just two days ago!) and will leave in about 3 weeks . We are following that with a two week Tauck tour of Israel and Jordan, so would like to minimize the clothing that we take just for the cruise. Are jackets and ties required on the formal or other evenings?
