We have a birthday visitor from overseas (England), a nine year old. Her family is here and hoping to visit Disneyland with free admission for the birthday girl. However online details appear sketchy about the admission requirements. She has a passport. Registering ahead of time seems impossible as she is under 18. Can anyone clarify that if she visits (with her parents) Disneyland with no pre-registering but simply her passport (and her parent's passports) that she will receive free admission??
