How to ask?

I would say something along the lines of, “I’m getting excited, any updates on the rehearsal dinner?!”

You should have your FS reach out since they are their parents. Since they already offered to host, I would say "hey, I know you guys mentioned hosting the rehearsal dinner, is that still the plan?" That will open up the conversation.

Just say are there any updates with the reshareal dinner! So you would know whose coming and location. It's normal to be concern bc it's apart of your big day. Maybe add in is there anything they may need you or FH to do...

I agree 100% with Catyln, this should be a conversation that your FS has with them or the two of you approach it together (FS leading)

I was in a similar situation, and I ultimately just decided to say, "here is what I was envisioning, what do you think?" and we got excited planning it together. It can be pretty awkward, but its better to just come out and ask than to be stressed about it. Good luck!

I would have your finace reach out since it is his parents that offered to pay. He could kindly just say that you guys are almost done planning and wondered if they were still planning on helping with the rehearsal dinner. My mother-in-law told us she was going to pay for our rehearsal then never mentioned it again. She never gave us a budget for anything so I researched a bunch of different places. She came down to visit us then my husband bought up the rehearsal. I had several different menu options from different places and she helped select which place we had the rehearsal.

Thanks everyone. I have an update on my page if y’all want to see it! Thanks!
