We stayed for one night ages ago just to get the ferry. This time stayed for two nights for a look about. Arrived just as preparations were being made to update toilets and reception and yes it was a bit muddy but that's what happens when the ground gets wet. Just stay with the paths. Despite this we thought the site was excellent value, clean and staff very helpful and welcoming. Got local bus to Folkestone (very expensive) and had really good carvery meal at SUNA which is opposite McDonald's. Don't know much about children's facilities as we try to keep away from them.
