Coniston Park Coppice no availability

A week or so ago I checked availability at Coniston and there was nothing available from 3 Nov through till March 10.  I did query this with the club and was told there was going to be work in progress so site was probably fully booked. Being a bit sceptical (not a single pitch available for 4 1/2 months) I checked again today. The site info does now say that refurbishment work is taking place 3 Nov till 10 March so limited capacity, however now there are plenty of vacancies in Nov and Dec (upto 23 Dec) where previously there were none, yet no availability 24 Dec through till 10 March. I find it hard to believe there is not a single day in that period with availability. And why has Nov and Dec suddenly freed up lots of vacancies whereas there were none (has the refurb work been put back?). It suggests some pretty major work is going on - is the club telling us the true picture, just how many pitches are available Dec - March?
