Sandringham Estate Site

Does anyone know what is going on with the above?  We usually go there for Christmas but when I tried to book it earlier in the year, it was shown as closed between (I think) October and April.  I found out later (either on here or in the Mag) that it was due to refurbishment of the toilet block taking place during that period.  We were a bit disappointed because we have been going there for quite a few years now and really enjoyed the atmosphere over Christmas.

However, this morning - and don't ask me why I looked - but I did - only to find that pitches were now available right over the  Christmas period.  Needless to say, a quick cancellation of other sites booked was done, and now we are booked into Sandringham for Christmas once more

I just wondered if either someone had realised that the Club was going to lose so much revenue over what is a very busy period for that site - OR - is there a question mark over the renewal of the lease, thereby rendering an upgrade a waste of money?
