I have cruised several times, different lines, always with children, grandchildredn, stepchildren. I have always been told the same thing. However, not once has anyone ever asked or questioned the children traveling with me. I have never shown a paper regarding any of them. This procedure is much more watched when traveling by air (when you land in a foreign country they will ask). Cruise lines just don't seem to adhere to this procedure. Once again on June 9 with all these children I will for my grand children have my daughter notarize a letter simply saying "I ___ am aware that my children __ and ___ will be traveling out of the country with their grandparents ___ and ___ from ____ to ______. This letter also serves as authorization for any medical attention they may need." Still I have never been asked to show a paper.
