Crap, that's annoying! I was planning on taking DD one more time, and, while I've meant to do the upgrade for me about a million times, I just never got around to it... The time I added days onto my park hopper, the ticket agent dude at DLR said I could upgrade from a park hopper to an AP at any point before the first day of my first park hopper pass, and it would be good through that date... In other words, if our first day was 3/4/12, he said I could upgrade at any point, and my AP would be good through 3/3/13. I apparently REALLY misunderstood what he was telling me! Oh well! Thanks for the information!
