So one of of of my BM's is bringing one of her friends to come to the wedding with her and her husband. I do not know this girl and only met her once, when my BM went to try on her dress and brought her with her. I have all the bridal party and their SO's sitting with us, all at the head table. My question is, where do I put the guest my BM invited? There's BARELY enough room for all of us in the bridal party as it is, much less any extras. She doesn't know anyone else that will be there so I'd feel bad sitting her next to anyone else (even thought I don't even know her), but really don't feel like I should have to cram an extra seat in to an already crammed headtable just cause BM invited an extra person (not her husband). I guess I could sit BM, her husband and her guest together at a separate table, but that kind of defeats the whole keeping the bridal party together things I was going for.
