Before I retired I acted as an expert witness in several pool cases in the UK. My experience there was that the law needs to be complied with in FULL but apart from anything else I can tell you that really horrible accidents frequently occur in pools, causing death or permanent disability, and as soon as there is a pool people or children get excited and do very silly things. However the law makes the owner responsible. I am against the nanny state and elfnsafetee over enthusiasm but it's better to be safe than sorry, especially just for one week. It's not just pools either of course. Here in Brittany, especially in holiday periods, there are usually at least weekly accidents involving death or injury at sea. It's a pity you haven't got the sea nearby as geography can't be sued.
