HI everyone! I was wondering the policy on using up old tickets at the parks. We have tickets from our last trip in 2005, one adult and two child, that have two days in a park and two water park options on each. We wanted to use them for the water parks on our December trip - the question is this - will they allow you to use the water park options if our daughter is using the tickets for the park days or once they are assigned to her can only she use them for the water parks? That was a clear as mud - TIA for any help.
