They had them both the other night and yes, the timing was difficult. We ended up choosing F! since a few in our group had never seen it due to weather cancellations. We remained in the theater while the crowd dispersed and saw some of the fireworks from there but with F! at 9:00 and SW at 9:30 it was near impossible. Many people started leaving the theater when the boat with all the characters at the end of F! came out and I was guessing they were trying to get to a spot of the fireworks but F! was a higher priority for our group.
