Such a shame this has gone as my kids really enjoyed it, but agree the flooring and general area has looked neglected for some time.
There's a huge amount of disused land in this area, when you include the barely-visited animal paddocks and the unused car parking area. That's not even including the unused lake. Massive opportunity for expansion given the rail station is there. Money permitting, I would relocate or remove the dodgems, open up a circular lake walk, and develop the old car park, animal paddocks, and land where the Thomas exhibition used to be, into a brand new land akin to the likes of Bewilderwood.
