I have 3 days left on park hopper passes (2adult, 2 children) that were purchased in 2001. My ds is now 12 and dd will turn 10 while at the parks this Aug. I spoke to a CM yesterday and he said to bring their birth certificates and they would be changed to adult passes at no charge to me. I spoke to another CM today and she said that you have to pay to change them. Does anyone have an answer for me and if there is a charge do you know approx. what it will be?
