Fright nights this year say from £10, although all the dates I checked were only £10, which is cheaper than before. In July, there is no mention of any annual pass prices. So it’s either free completely, or you have to pay the £10 standard night ticket. I’m August it says £10 for a 10am-10pm annual pass ticket. The type of annual pass isn’t specified though, although because of that I’m sure Thorpe park ones are accepted.
