How can I get dad to participate in the senior center?

Ive brought my 92yr old dad who's been recently diagnosed with dementia, to Florida for the winter from Michigan. Its definitely an adjustment for him and I thought maybe getting him involved at the senior center, where they have activities for dementia patients a veterans club and other activities that he could participate in. We took a tour, he perked up a bit but after we left, he lost interest. I tried to explain that he can go there just a couple days a week and that it's better then him staying home watching TV. Hes always been active but this last year, he's lost his lady friend, dementia, TIA attack and me spending the summer with him and now bringing him to Florida.

I know it's a big change, I've noticed that his memory loss has increased along with questions. Hes cried here and there, asking when is he going home and I explain calmly that we'll go back to Michigan in April. I just want my dad to be happy, be active again and not be in this "I give up" mood. The "I've already lived my life " mood. It's sad to watch.

What can I do to, if anything, get him to go, just give it a try, I've even tried reverse psychology..lol..that didnt work. I get it, different place, and just wants to stay where i am, as i am his security blanket right now.

plus, it'll give me a little break too, I've noticed the clingyness. And he feels like hes become a burden, and I've explained that he is definitely NOT a burden.

So for now I'm looking for things I can take him and we can do it together.
