For mine and for lurkers' sake, what are the quick "dos" and "don'ts" for rehearsal dinner etiquette? My FILs are hosting at a nice restaurant, and FMIL has been asking me about the guest list. I know that all the WP members and their dates should be invited (all siblings are WP members), along with readers, and obviously parents and grandparents. I have read in some places that one ought to invite OOT guests, also, but as nearly all our guests will be OOT (about 120 of them, if they all attend the wedding), I wasn't sure how that would work.
As far as extended family members, FI has a number of other relatives (twenty-five people counting aunts, uncles, and cousins) who have all verbally said they plan on attending the wedding and reserved rooms from our hotel blocks already. At least one aunt and uncle will be invited, since they are the caretakers for one of FI's grandmothers who is in a wheelchair and needs the assistance. So I think FMIL is trying to figure out how to equitably invite relatives due to this. I only have 5 other relatives (aunt, uncle, and 3 cousins) attending the wedding apart from my parents and 2 brothers (and all my grandparents are deceased).
I don't think the family sides need to match in numbers, any more than BMs and GMs need to match. But I think FMIL feels weird hosting a party that will involve mostly the groom's family and so few of mine. Thoughts? And any other pieces of information I should keep in mind/ relay to FMIL as I work with her in trying to help arrange the details on the rehearsal dinner?
