Rehearsal Dinner: Who gets invited?

Typically, anyone attending/participating in the rehearsal gets invited to the rehearsal dinner (wedding party, officiant, readers, etc), plus immediate family.

My future MIL is hosting ours, and, in addition to the above, she’s inviting extended family members (that have arrived early/are in town) to attend.

Just the wedding party, readers, officiant, and immediate family.

Our wedding party and their significant others, our parents and grandparents, our officiant, the ring bearer and flower girl and their parents/siblings. I think it came out to 38 total including all of them, us and my son.

Our wedding party and their spouses, our parents, siblings and their spouses and kids (they are the flower girls and ring bearers) and potentially my aunt and uncle because they are from out of town and will be staying with my parents.

Bridal party and their partners/plus ones. Basically anyone who was at the rehearsal.

Anyone in the rehearsal should be invited along with their significant other/ date, and if you have minor children in the wedding (i.e. ring bearer or flower girl) then their parents get invited. Then parents and grandparents are next on the list. Some will do extended family, and some invite out of town guests if most of the guests are local.

We invited the wedding party, family members, and all out of town guests. A lot of people just invite the wedding party and immediate family, which is also fine

Just the wedding party, their partners, our parents, and one out of town family member who’s staying with his family. 15 total.

We invited our immediate family, wedding party, and their significant others.

It's the people you want to thank for attending the rehearsal and their SO's. The rehearsal dinner is meant as a thank you. People do expand that to other VIP's in addition to that. The dinner doesn't have to be fancy. Any food and drink that is fully hosted is great.

The people invited are anyone actively participating in the ceremony, including the officiant, and all significant others. In our circles, they are also very casual such as pizza or Chinese food and dress casual is as fancy as anyone gets. We have never seen the bride dress up or wear white. In our circles, a welcome party for additional traveling guests is not done. If they were hosted, that would be an additional $$$$ that not everyone has and no one would dare invite anyone to a party and ask guests to pay their way.

Our bridal party and groom party are invited also parents. Wedding officiant

For ours, it was immediate family, the bridal party, their plus ones (who were one and the same in some cases), and my mother-in-law also invited all of our guests who came in from out of town. Not all of them were able to make it, but some did. We did invite our officiant and her husband, but she opted not to come so she could rest her voice the night before.

Traditionally, you include parents of the bride and groom along with their partners/spouses and everyone marching down the aisle and standing up with the bride and groom during the wedding ceremony, including grandparents and clergy. Anyone who is at the wedding rehearsal should be invited to the rehearsal dinner, along with any out of town guests. This dinner is usually paid for and planned by the groom's parents/mother. If you are fortunate, the groom's mother will consult with the bridal couple when planning this dinner, although she doesn't have to.
