We’ve just got back from another great stay, we love that you get your own key to the special gate to go into the grounds of Chatsworth, the only slight problem we had with the key (pitch 14), was that we had a problem unlocking the door from the the side of the estate grounds, we had no problem unlocking/locking from the site side of the gate or locking from the Estate ground side, hubby told one of the wardens about the problem with the key & was told you need to put the key in gentle & lift the key to which we did but still had a problem unlocking from the estate side of the gate, for the first few days we were with another couple who also stayed on site in their caravan even they had trouble opening the gate with our key, but when using their own key there was no problem unlocking, this is the first time we have had an issue with the key, all the other times we have stayed we have never had this problem, maybe it needs looking into, would be interesting to know whether anybody else has ever had the same issue with the key for pitch 14, other than the issue with the key a fantastic time was had.
