Could you contact your local alzheimers society and see if there is anything suitable , i suppose it depends on what kind of things he wants to do,as most day centres have to cater for the majority, What about a bowling club is there one in your area and you could go as well,
My husband was only 63 when he first started to go to a day centre and everyone else was much older he was a very intelligent man and has had to learn to fit in with them,he refused to join in anything at first but he now joins in rather than sitting bored,
What about finding someone who could take your husband out or do something that he wants to do in your home it is expensive but seems to be the only alternative,
I hope you find something suitable ,
