Merlin will not make a decent effort because they know they can get away with being half-arsed at everything they do, from operations to maintenance to pricing and even park atmosphere/themes, purely because they have what is essentially a complete monopoly over the UK theme park industry. A recent example could be their treatment of colossus and one of its pit areas that, as far as I can make out was flooding and they decided to concrete it, completely detracting from the theme because it would save water being pumped out. Oh, and Heide park's collossos which they let get infected with woodworm rather than implementing proper fail safes. Then you have Alton, where all you have to do to get an impression of their attitude is to use the monorail from the car park, with its windows and peeling decals that look like they haven't had any attention in years. Great first impressions. I haven't been to Chessington for a couple of years now and currently have no intention of returning in the immediate future, but hopefully Paultons park will give them a bit of a wake up call with their new tornado springs area and take some business away so they make more of an effort.
