My parents' are paying for my wedding ceremony and reception, and my fiance's parents will be paying for the rehearsal dinner. We have not made any plans for the rehearsal dinner. However, my fiance's parents only want to invite the bridal party and immediate family (not out of town guests), which was fine with me because we have a lot of people coming from out of town. My mom just forwarded me an email that she sent to her (out of town) family with the details of the wedding times, etc so we can get a rough count before we even send out invitations. In the bottom of the email she added "There will be a rehearsal on Friday with dinner to follow." I am frustrated that she added that, but it is not like she can take back the email, so what should we do? Do we have to invite out of town guests now that she said that (we are talking probably a 100 person rehearsal dinner for a 150 person wedding if so)? She, of course, offered to pay for these people, but I am afraid this offer will only offend my fiance's parents, plus, this invitation will probably make them feel obligated to invite their out of town guests as well, which still adds to the cost they will have to pay. What do you think?
