In fairness, I doubt that Alton Towers have “decided” that The Curse at Alton Manor and Hex can’t operate together.
I imagine it’s more likely to be very poor luck, and a wild coincidence, that the two haven’t operated alongside each other very reliably.
I remember pre covid going on tiger rock with a friend who had to leave the station to go to the loo - it was a busy day with a queue of well over an hour - I assumed and had no issue sharing a boat with others but they just stuck me in one by myself which is ridiculous.
I love Paultons Park and I hope it continues to excel as it has been doing in recent years but this country needs more competition when it comes down to theme parks. Merlin I feel are far too complacent because they have the monopoly and in turn it feels like they really don’t care if guests have an enjoyable day or not. It’s seems to be all about £££
It does seem at the moment that Chessington doesn’t have the best reputation in terms of ride availability and ride reliability - Jumanji area looks decent enough. The fact they have a soon to be opening B&M coaster (something I never thought I’d see) is brilliant but it’s not great if majority of the other big rides aren’t available.
I only visited Chessington twice last year and the last visit was unbearable - one of the worst days I’ve had at a theme park (thankfully I was with a friend, her little boy and her partner so the company was fab).
Hopefully things will improve but only time will tell
