Minors onboard must be supervised by a parent or a legal guardian at all times and are welcome at the activities onboard or at shore excursions, provided that a parent or legal guardian is present. Guests under the age of 18 are prohibited from disembarking the ship unless accompanied by a legal guardian or an adult duly authorised from the legal guardian to accompany the minor, by virtue of an official consent of the latter. Children cannot remain onboard if their parents or legal guardian go ashore, unless expressly authorized by the onboard staff.
