Hi

We have tickets left over from our last trip four years ago when the children had kids passes.
I have been told that I can have the kids passes upgraded to adults for free for them.
I know that I would have to have this done at one of the customer service desks but which one would be the quickest and easiest to get to as we are thinking of getting this done as soon as we get off the plane before we go to the accomodation as we also don't know how many days we have left on them either.
We are flying into Stanford and staying on International Drive.

Thanks

Michelle
