Seating Charts- Who sits with who?

I'm going to have tables for family and put my friends together that know each other. Its not easy

I'm thinking about it. I'm having a small 65 people wedding so I'd say most of them could seat themselves. But overall I'd do households or age. Example would be my fiance has a lot of cousins so I'd seat all his cousins together, and then his aunt's and uncles together. Then who knows who, I have two sets of friends who adore each other so they'd get a table with their kids. My single friends will probably get their own table to hang out at.

I was planning on doing open seating also because FH and I thought it would be easier. I did some research and we changed our minds. We are just going to assign tables and people can pick who at the table they want to seat with. We are keeping families with family and like all my co workers together.

Im mixing it... Basically I'm sitting people with others that I think theyll have a good time with. Some may have households where as others will be with siblings and such

I haven't talked to my fiance about this topic yet, but I assume we'll do like aunts, uncles, cousins from each side together and then like different groups of friends together etc.

Since my family is enormous and his is quite large as well, we can't afford random plus ones, so I'm thinking of trying to keep families together, for the most part, but also ensuring that those who come alone are seated with their favorites.... so like, the hot fun female cousins will probably all be together, the bookworm cousins will all be together but alongside their spouses, etc. However, I have no idea how this is going to play out in real life!

I have literally re-wrote and scratched up my draft...I am trying to do it by association. Like we have older guests that know the other older guests and am trying to keep them together and vice versa for our younger friends/family!
