I’m one of 3 bridesmaids, 8 party-goers in total. We said in December it would cost £250 for a weekend away, we checked before booking that everyone was OK with it, nobody dropped out.
Now one of the girls says she can’t pay. Her partner has been made redundant and she is in debt to her parents for just covering bills and running her car. But, she already been paid for, on one of the other bridesmaid’s credit cards. It’s non-refundable. We can’t raise the price for everyone else after saying £250 was the upper limit. I’m the only bridesmaid that knows her and I feel like I am going to have to pay for her in the end. I have been saving for a holiday for me and my son and if I have to pay for her we can’t go, or at least we can’t go for as long. I worry that this whole situation is going to either ruin my friendship with this friend, or sour the hen party if others have to pay more for her. None of it is my fault but I am probably going to have to cancel my holiday to pay her debt to keep the peace 
What can i do?
