the line for TSMM just before fireworks can be even shorter than just before closing time.
With Star Wars fireworks at 8, they will probably be closing TSMM around 7. We learned during a recent visit that this is only an estimated closing time. They have to have the area cleared 30 minutes before the fireworks show starts which means that they can leave the attraction open beyond the stated close time if the line is short. We arrived at the ride 10 minutes before the "closing" time and were able to ride 3 times before they officially shut the gate and cleared the area. We still had plenty of time to find a good spot for the fireworks then the late showing of Fantasmic.
