~ I'm not sure this is right. The reason I can be so certain is because of what happened in either 2002, 2003 or 2004 (I forget which). Basically the first weekend of fireworks were hit by bad weather. It rained all day on the Saturday from start until about half an hour before the fireworks show. (It was estimated that over half of the guests had left to head home before the fireworks due to the dreadful weather). On the Sunday, rain had been swapped for very high winds. The park opened with a handful of indoor rides open, but the entire park was closed by lunchtime. (I can remember this as we all got sent home & were paid until 8pm). As a result of this closure, the park had a fireworks show in hand, so they ran fireworks on the following Thursday, Friday, Saturday & Sunday. (i.e. added a Thursday show onto the planned last 3 days of season shows). You are correct when you say the Friday fireworks were the quietest as kids were in school... which would not be the case if it was the Friday of the first fireworks weekend, which as you say normally fell in half term. I always used to go for at least the late afternoon / early evening & fireworks on the Friday as it was quieter and quite bearable. Also, the Friday fireworks was the only one of the 5 firework days when local resident tickets were accepted, they could not be used on any weekend fireworks day as the park could fill the place to capacity with paying guests.
