My fiance's parents are hosting the RD. They'll be in from out of town, so I sent them info on possible venues for the RD and lists of wedding party people to invite as asked. My future MIL let me know that she's willing to pay for only wedding party and spouses plus 2 of her other grandchildren, and that she is willing to pay for food only and no alcohol, which is cool. She's hosting/paying and could do it at McDonalds if she really wanted. I will have some family in from Germany and Australia and I'd really like to have them at the rehearsal, but I think it'd be rude of me to tell them they can't go to the RD. And I'd like people to have the option of a glass of wine with dinner if they choose. Would I be out of line to ask her to split the bill, or let me take on those extra expenses? Or should I just not invite my out of country family to the rehearsal at all, which I wouldn't really want to do?
