Travelzoo Tip: The Gem also boasts NCL's famous "Freestyle 2.0" cruising. This means champagne at embarkation, upgraded bedding and bathroom amenities, and lobster on the main dining-room menu. Leave your tux or gown at home (but only if you want to), because formal nights are optional. Other cruise lines assign you a dinner time and seat you with strangers, but NCL lets you eat whenever and with whomever you wish.
