Hello! We're having a wedding ceremony and reception in a relatively accessible place for where our family members/friends live. In fact, we're probably going to have 85-90 people out of the 125 we invited, which is quite a bit for DW I think! We decided to have a destination wedding because we wanted a smaller wedding, which we sort of got. Anyways, so my fiances parents invited about 16 of their friends (all of which are coming, and this actually led to me and my fiance having to cut some of ours due to venue size, but that's a different story!) Now my fiances parents are talking about having another party when we get back (they live in a different city) for their friends that were NOT invited to the wedding. I feel like this is kind of rude to a) their friends who will feel like b-listers and b) my parents, who are throwing us a lovely wedding. Obviously, I would never argue about this with FMIL and would put on a smile and attend, but I can't help but feel like this is a tiered reception and uncomfortable with the whole thing. Is this improper etiquette to have a party like this??
