I went to a pre covid wedding and they didn't even have a dance floor or dancing. honestly most guests were able to just mingle amongst themselves ya know? but they had a photobooth and some things where guests can leave date night ideas and advice jar and what not. my wedding was pre covid and i really wanted a magician but in the end i didn't get one because i spent the money on a DOC instead. but i imagine something like a magician would be helpful in entertaining the guests
Without dancing, I’d probably just let things flow and end the reception early, if needed. But the activities you have in mind sounds like enough to me. I say that because people are going to naturally mingle and chat with one another, especially if you have a nice music playing in the background. So trying to fill the entire time with an activity isn’t necessary (plus it might feel a little like forced “fun” if you have too many activities). Lol!
