I went to Chessington the other day and it was pretty good. I'm just saying this because I had heard the park has been pretty atrocious this year, but actually they were running things well and aside from Fury, everything was open at 10am. There's clearly staffing issues with platform staff having to shout at guests from afar to batch rows on Vampire and Tomb Blaster.. which for me just comes across as unprofessional.
But they were making the best of a bad situation which I can't really blame them for.
