I'm taking my grandchild or a child who isn't biologically mine
If you're travelling with a child who is not your biological child you need to bring a legally affirmed letter with you. This includes grandparents taking their grandchildren on a cruise without the child's parents. The letter from the child's parent or legal guardian must authorise you to take the child on the cruise, sign any sports waivers, and agree to any medical treatment needed. It must be affirmed by a solicitor or Commissioner for Oaths. More details, including a template of the letter are available here.
Child's surname is different to mine
If you're the parent and your child's surname doesn't match yours, you'll need to provide proof of parentage. Please ensure you bring a copy of the child's FULL birth certificate – showing yours and the child's names – and any other official documents showing the reason for the different surnames – i.e. divorce papers, marriage certificate. Legal guardians will need to provide certified proof of legal guardianship.
Can my children sleep in a different room?
Under 21s – or under 18s if sailing outside North America – can only sail if they're in a room with a guest who's 21 – or 18 if sailing outside North America. The only exception is when they're next door, or immediately opposite, their parent or legal guardian.
