Park Pass Question

[Tinkermom]

I have 2 child park passes from about 5 years ago and each have 2 park days left on them (these passes do not expire). Does anyone know if I can upgrade these to adult passes and if so what would the cost be? Thanks!

If you take them to guest services they will upgrade them at no cost. That is what they did for me when my son transitioned over to an adult at 10!
