We just used a FP for this last week and were very glad we did. We love the show but hate the line. I would recommend using FP+

.
The FP entrance is next to the stand by entrance. Both sets of lines will enter their "holding areas" at the same time. The FP "holding area" is to the left and standby is to the right. When it is time to be seated the FP line goes in first and standby follows. We were seated in the center in the Mickey section.
