Where to seat my parents and his?

It's totally up to you. I've seen it done both ways, where both parents were put together, or one table with your parent's and their family and same for the other side.

I'm going to put my FH's parents with mine and then another 2 couples their age because that will be the first time they're meeting and I think they should share in that together.

We split the parents because my parents live in Michigan and rarely see my Gma, aunt and uncle.

I hope my girls sit us with our family. We see their FIL's on a more regular basis than some of our OOT family members.

Each set will probably be at their own tables, so they have more options as to who gets to sit with them.

For my wedding, I was planning on having them seated separately that way they can sit with our grandparents and other close relatives. Both tables will be right in the front too.

FH has two sets of parents that do NOT get along in any stretch of the imagination so there will be three parents tables I have to figure out lol.

My daughter the bride & her FH will be at a sweetheart table. The groom's parents & family will have a table. My mum & family has a table. My husband's folks & family has a table. And we seated our good friends, who we get to see about once a year, with us. The bridal party are sitting with their own families as well.

We worked with our parents to sit them at tables with their closest friends/family. We figured to sit family together, and they can mingle on the dance floor.

We did each set of parents with their own family

I looked it up at some point and I think tradition is they are sat together at the reception with the officiant/officiant's spouse. There's some symbolism there with how they are on opposite sides at the wedding and then the families are joined together by them sitting together at the reception.

I don't think it really matters though. It depends on if there are other people your parents will more want to sit with (friends or family they don't get to see as often) or just how close your sets of parents are.

At mine, our moms are BFFs so both sets of parents will be sitting together along with FH's sisters (who are all unmarried and still live at home), and possibly FMIL's mom. I'm kind of expecting them to get up and move around and talk to family and friends they don't get to see much, so it's probably just for the meal.

We had a sweetheart table and sat my parents and uncles/aunts at table 1 and DH parents and uncles/aunts at table 2. The most important thing is to sit people together who will get on well together

Our parents are sitting with their respective families.
