Over the past few years Disney had become fairly lax in enforcing the return times shown on FASTPASS tickets. If your FASTPASS return window was, for example, between 1:00 pm and 2:00 pm, the vast majority of Castmembers would accept that FASTPASS any time after 1 pm until the park closed.
That seems to be changing. In tests over the past week at both Epcot and the Magic Kingdom, we were denied use of FASTPASSes that were no more than 3 hours old.
We make limited use of expired FASTPASSes in a handful of touring plans, and we’ll be updating those plans to a better FASTPASS use strategy in the very near future. In the meantime, readers should assume that Disney will not honor expired FASTPASSes.
