Reply To: JCCC2: The encouragement of Formal Night(s)
From the HAL FAQs:
Evening dress falls into two distinct categories: Formal or Smart Casual. Smart Casual can be defined as slacks and collared shirts for men and casual dresses, slacks and informal evening wear for women. T-shirts, swimsuits, tank tops and shorts are not allowed in the restaurants or public areas during the evening hours. On festive Formal evenings, ladies usually wear a suit, cocktail dress or gown and gentlemen wear a jacket and tie, dark suit or tuxedo. There are approximately two formal nights per week.
Formal wear is (in theory) enforced in the Main Dining Room on formal nights. You could eat at the buffet on the Lido deck, or order room service, but experience of dining with fellow sea monkeys is not to be missed IMO.
