I am starting to get really stressed about some guests that we feel we 'have' to invite but quite honestly don't want four people we barely know at our wedding reception. Its OH's step sister and brother plus there partners. We are expected to invite them even though there is virtually no contact apart from family get togethers and we don't even speak to them then. Our evening party is going to be around £17 per head so its a lot of money to pay for four people we are not fussed about. There is the possibility that the SS may not come as she is having a baby, due date our wedding day but I think we would still be expected to invite them. We already invited them all to Cyprus for the actual wedding but after messing us about they decided not to come, didn't bother to tell us either we only find out information through OH's mum. So im wondering what do you think I should do and what would you do ? Or have done in a similar situation ?
