You cannot base your fireoworks plan from last years Oct schedule...
They ran a test program for about 3 weeks from mid sept. Originally, fireworks and spectro were scheduled only on Sat. The test program was, 1 week fireworks daily, 1 week spectro daily, and 1 week alternating fireworks and spectro. We went during the alternating week. For the dates you are going, I would expect fireworks and spectro Sat only and anything else is a plus. This is also the time of year they reintroduced EE. (they did this all for out trip).
It is possible this was all done becuase attendance was starting to pick up and they could afford slightly extended hours. Also, the test ended when
MNSSHP started since there is fireworks on those nights.
