If children are joining you on a trip without their parents or guardians, you should obtain a letter of consent to travel before you leave home. This letter proves the children have permission to travel with you. While you may never be required to show this letter, it’s important to have one just in case.
Health and safety standards and building regulations may vary widely in different countries. Please don’t assume everything is children friendly. You should supervise your children at all times while moving around.
