You can’t fill your own water bottles direct from the machines in Kings Court. You would need to fill up glasses then pour the water into your bottle. There are notices reminding you of this and sometimes crew members on duty at the machines. I am not sure what you mean by an all inclusive vacation. To me that implies drinks are included which except for juices, tea and coffee in Kings Court, all other hot,cold,alcoholic or non alcoholic drinks are for purchase either pay as you go or via a drink package.
