We had two two day MYW tickets we forgot to have taken off keys to the world keys last September, we used our APs during the trip. I just remembered about them a couple of weeks ago! I called Disney and got extremely lucky. The first call I was told it may or may not be fixed, but it would have to be in person at Guest Services. I called back, explained my situation to someone else and they gave me a different number to call. I called that number ( sorry, I don't still have it) and got the best CM ever! She found our tickets from our reservation number and let me combine the two of them towards a 8 day hopper ticket! I was charged the difference which was around $3.00. She had the ticket mailed to me and I received it last week. It never hurts to call and ask and if you don't like that answer, call back and ask again- you never know it worked for me. Good luck.
