9) Are children allowed to stay in a Marella Cruise cabin without adults?

If you're travelling as a family, it's a great idea to book cabins next to or opposite one another. If you have more than one of these cabins, then children aged 12 or under will need to be accompanied by an adult. For separate cabins, under 18's must be accompanied. For itineraries that include a port of call in the US, under 21's must be accompanied.
