So originally my fiancé and I decided we wanted a small wedding-no more than 150 guests, and finally we found a venue that we love...which only has a 150 person capacity...unless we want to DOUBLE our food and beverage minimum. As a result, we started working more seriously on our guest list to ensure we don't go over the 150 person cap. Despite relentlessly bugging our parents about getting together a list of people THEY wanted invited, neither side has produced anything in the 7 months since we've been engaged...until I got super excited about this venue. Since we found this venue, my mother has constructed a list of 30 additional guests (which would not meet the food and beverage minimum of the next largest hall) and insists we allow all 71 children (my fiancé and I had already made the decision that we wanted no children at the wedding BECAUSE of how many there are and that we intend to pay for the wedding ourselves.) We finally reached an agreement that only a select few children would be invited including 3 from a guest from out of state, all 5 from my fiancé's side, and 2 of my mother's cousin's (also her boss) children. I have no problem with the 3 from out of state or the 5 from my fiancé's side, but one of my mom's cousin's kids is a complete brat who I can't stand, and my mom's cousin has several other siblings with about 20 children between them that will likely cause conflict on the big day if their nieces there but that their own children weren't allowed. I have already expressed my concern to my mother but she wants me to just not worry about it and direct anybody who has a problem with it to her. I just don't know what to do. Any advice would be appreciated!
