On the park's side, there isn't a huge incentive to make things better for annual passholders, they already have their money. Will be interesting to see what the renewal rate will be like for next year. To some extent the park would be better off with fewer AP holders anyway. I'm not saying they shouldn't be running the park better (operations are definitely bad) just that there isn't really a huge incentive to keep AP holders happy.
On the queues, are they actually significantly worse than a year ago? Or are people just expecting shorter waits doe to the "reduced capcity for covid"? If the queues are under 90 minutes that seems what I would expect for school holidays, if they are over two hours regularly then there are problems and the complaints feel more genuine.
Yes Chessington needs more high capacity attractions, but is the product actually worse than a year ago?
