At MK, there was an AP specific tapstile line that I used for ETPE a little over a week ago. It was the furthest right tapstile of the tapstiles on the left half.
At EPCOT International Gateway, the tapstile furthest on the right is AP specific, but I forget if signs were up designating it as such during ETPE.
I remember seeing one at DHS before, but didn't notice if it was up when I went through ETPE recently. I didn't see one at DAK, but wasn't looking for one there.
