I ran into the turnstile annoyance after upgrading my Maple Leaf "7-day" (really 14) to a Preferred AP last week. After several days of entering both USF and IOA, and using the lockers at FJ and MIB, and visiting three Disney parks, suddenly my finger wouldn't scan with my new AP. I raised my wrist, relaxed my wrist, pressed harder, pressed not as hard...no dice. Fortunately my name is printed on the AP so I just had to show identification. But it reminded me of those discounted Ticketmaster tickets from a couple of years ago: they weren't in the Universal computer system apparently, so that was a total pain when trying to enter either park.
