I would say that it is not a bad thing to be repetitive especially when it comes to people living with dementia, activities such as music, smelling games, reminiscing, old school board games, puzzles, painting, they all make up a big portion of my week, then I try and do sessions such as dancing, parties, and other bits and bobs.
I find that the repetitive sessions are the best ones as people know what they are doing, and there are so many different ways to deliver one session, for example singing. You could have singing every single week, and you could do a different theme each week, or have different songs each week, different people being the song selecter, different movements to the dances that go along to some of the songs.

I would speak to the people/carers of the people who are visiting, ask what type of things they would like to do :)
