Parents friends invites

Not counting distant family that I don’t have a relationship with, my parents want to invite 20 of their friends Ann’s fiancés parents want to invite 24 of theirs. This means half family, and almost half our friends and half parents friends ….


I am very keep the peace and make all happy but I’d really prefer to cut like 25 to 30 guests given it’s like backyard venue, buffet style on plastic ware, aka the vibe was meant to be intimate and not networking event to impress. We didn’t assume any financial help but it ends up being 1/3rd us, his parents and mine just about. Still, half is family… would you throw down to make a little cut or just go with the flow hoping not all distant people show up?
