I am having a small (60 total) wedding. My venue is small and private, and I already have my centerpieces and table things done, so adding a table is not an option. I have a problem with one key guest (my soon to be mother-in-law). She causes a lot of drama for a multitude of our guests and everyone is requesting specifically to be sat no where near her. I have two open seats at her table and two people on her side of the family that do not currently have a seat; do I put them together hoping not to have drama, or sit them at the ends of other tables making things a bit crowded? Any other options? I have tried talking to her about not starting any drama on our big day but she has not accepted. I am not stressing on any detail about the big day as much as her presence. Does anyone have any advice to help me with an unruly mother in law???
