My sibling with early onset Alz is in a care home and bored, but he cannot live on his own. Any ideas to keep him entertained?

My Brother has been placed in a care home but he is very resentful and feels trapped. On my visits he spends the entire time asking when he can go home and complaining how bored he is. He does have Early Onset Alz and although he has memory issues and hallucinations (being treated) he is fairly competent thought wise. That said, I don't think he could succesfully play a card game or something like that as the memory issues would keep him from remembering the rules. He will not participate in any of the activities they do with the elders there as they are too babyish (he isn't wrong), I cannot visit everyday but when I do, I would like to be able to do something he might enjoy. I am a little afraid to take him on a day trip as he is much larger than me and perfectly healthy other than his failing brain and he has had physcotic breaks. (I am his sister).

Any ideas?
