We are cruising for the first time on NCL and first time with our boys (14, 14, 12, and 3) next week, and I’m starting to stress. How much freedom do people give their teens and tweens on the ship? Where do folks/kids carry their room keys? Is there a lanyard for phone/key that you love? How about passports when at ports? How is the app for keeping in touch with kids? How dressy do kids get for meals? Are khaki shorts and a polo shirt ok for main dining rooms? What do you do with kids during shows if Splash Academy is closed at 6:30 and at 10?
