RECOMMENDED ATTIRE
For women: sportswear, casual dresses, skirts, pants and capris, blouses and knit tops. Light fabrics such as linen, cotton, silk, and wool gabardine are always appropriate.
For men: sportswear, collared golf and polo shirts, shorts, pants, and a sport coat if desired (not required). Light fabrics such as linen, cotton, silk, and wool gabardine are best.
For Discoveries, Aqualina and Prime C Restaurants: No bare feet, ball caps, tank tops or bathing suits are permitted in these areas. Shorts and torn/distressed jeans are not allowed during dinner.
For everyone: Be sure to pack a sweater and a lightweight wind breaker for cooler mornings and evenings. And don't forget your workout clothes! You will also need a pair of sneakers or rubber-soled shoes for deck sports, and a swimsuit and cover-up. You may also want to pack more conservative day/port wear for onshore excursions. This clothing should be culturally appropriate for museums, restaurants and religious sites.
