Passenger demographics vary by the time of year and itinerary. In general, older Gen X and younger baby boomer passengers are in the majority on the ship. Families with children are in the minority year-round, but are more common during winter and spring breaks on the Caribbean itineraries and during the summer for Mediterranean voyages.

The dress code on board is usually "cruise casual." In the evenings, approximately 10 percent of passengers wear jeans, but most wear khakis and casual dresses. Expect one formal night on which most men wear suits and women don cocktail dresses, with only a few opting for tuxedos and long dresses. One "smart casual" dinner night brings out the dress slacks and blouses. Baseball caps, swimsuits, tank tops, T-shirts and shorts are never allowed in the restaurants in the evening.

Each passenger (of any age) on all Royal Caribbean cruises is automatically charged $14.50 per day (or $17.50 per day for suite passengers). Gratuities can be prepaid or will be added to the passengers' SeaPass accounts while onboard. Passengers can modify or remove their gratuities by visiting the guest services desk onboard. An 18 percent gratuity is automatically added to all beverage tabs. In addition, passengers who select the My Time dining option must pre-pay gratuities.

Note: Australians and New Zealanders do not have the stateroom service charge added to their account; fares automatically include this gratuity as long as the cruise was booked in AU or NZ dollars.
