What's the crowds been like compared to past Firework events?
Compared to previous years I would have said it was pretty quiet. In previous years, capacity closures could be threatened, but it never really got close to that kind of level.
Most days during Scarefest half term week were far busier both during the daytime and later in the evening. Of course there is always a perception that fireworks will "feel" busy due to everyone congregating in a small area at the same time.
Queue times at the rides didn't get too exceptionally long during Fireworks, except for perhaps very temporarily in the rush after fireworks ended, and for some of the rides that operated during the time most others were closed (notably mine train in close proximity to the fireworks).
