We were in WDW in May and had several old passes. My DS, age 13, had an old child's "punch" type pass with his picture on it(he was age 5 or 6) with several days left on it. The CM at the Guest Services window at MK made a joke about how much he had grown and updated the pass to an "Adult" for NO CHARGE. We also had several old "punch" type passes (bought way before AK) with a few days left on each and the CM changed them to the new strip passes that DID include AK for NO CHARGE. My DH and I had APs but my DS used all the converted passes, even at AK, with no problem at all. Hope this helps!
