I usually never tell them what is on so they dont get the chance to say we dont want to come, so they come because they are curious. Have had a few that never come down so I have asked if the cleaners could clean their room. While they are waiting for the room or rooms to be cleaned they get brought into the lounge or where the activities may be. The first few times they watch then curiosity gets them and now they are atting slowly. Better than not at all. If you have time build a repore with them so they think that you have got time for them..Don't give up they will come around.
