My MOH is asking me to think about my guest list soon-ish so they can book... I know I want a small group thing, as does FH, so not sure if that makes a difference to the etiquette here. I do feel like if one of us invite a sibling, we both should.
FH is inviting his best man, and his two other closest friends. They're doing a ski weekend or similar sporty thing. He knows my brother very well, although doesn't see him without me there. Is quite happy to invite him if I want him to, but isn't fussed about it. I'm pretty sure my brother would go if invited but also wouldn't be expecting an invite so no dramas either way here.
MOH is surprising me with my hen, it'll be a weekend thing with an overnight element as far as I'm aware. So far I've only met FSIL twice. At the moment I'm including MOH, two bridesmaids, and two guys who are 'honorary bridesmaids' (usher and officiant in official wedding roles). If I invited FSIL I'd invite another one of my close female friend that I'm tempted to include anyway so neither are the only ones not in the wedding party.
Basically I'm just not sure if it'll feel super awkward having FSIL there, partly because I will probably be stuck rooming with her over one of my friends as I'm the only one who's ever met her (I have no issues with her just simply do not know her) and partly because we'll probably be spending all weekend talking about her brother potentially not in the most PG terms... which makes me err against siblings and going for friends only. Equally, there's part of me that feels I should invite her in the interest of extending the 'we'll be family soon' olive branch and fears it comes across rude not to... torn!!
