"Wow!" shouts Louis as we round the cliff road at Porth and see the waves crashing on the vast beach below. The hotel looks, appropriately, rather like a hospital. The sun is out and guests - resigned-looking thirtysomethings draped with muslin squares (for wiping baby vomit off shoulders) - are enjoying a lunchtime barbecue. In spite of screaming children careering into tables, the atmosphere is relaxed. People move slowly, talk quietly, smiling, like invalids relieved they are finally getting the treatment they need.
