One room among many
White Heath is a hotel with a gaming lounge in it, not a casino with beds attached. If you never go downstairs, nothing about your stay will be poorer for it.
Six hundred and ten square metres, one flight down.
The Signal Room takes its name from Signal Hill, which stands directly behind the house and carries the 1940 centennial memorial at the top. The room itself was the cellar and the laundry of the original house until the 2009 refit dug the floor down by 700 mm and put windows into the light well on the eastern side. It is the only part of the building where you will be asked for identification.
It holds 46 gaming machines and nine tables. Behind it, through a door that is normally closed, the Sandymount Salon holds three higher-limit tables and six machines, and is opened on request or when the main floor is full. There is a bar at the western end, a supper counter that runs until an hour before close, and a terrace off the light well for anyone who wants five minutes of cold air.
Entry is free. You do not need to be staying in the house, and you do not need to play anything to sit at the bar. What you do need is to be twenty years of age or older, and to be able to prove it.
