FI and I each have a good number of cousins who are all close. We're thinkig about doing cousins tables (everone is about the same age and I think they'd enjoy that more than sitting with their parents) We're talking 20-30 year olds, not anyone who will need help or miss mom or anything. As long as we keep them with their various SO's is that okay or does that go against a "splitting families" rule?
