Re: documents required- You must have a letter signed by at least one parent of the niece. The letter states name of ship, sail date and itinerary. It gives you permission to take the child, sign waivers onboard and seek medical attention. It must be notarized.. If parents are divorced it’s better if both parents sign
We just returned from cruise with teenage grandchildren and we were asked for the letter at checkin and they made a copy of it.
A passport is better than a birth certificate.
