So my sister (MOH) has been planning my bachelorette party for the last 5 months and we are supposed to leave tomorrow for a weekend at Lake Travis in Austin, TX. My other bridesmaids have been involved in the planning from the beginning, discussing costs, activities and travel. I thought I was getting so lucky because all of my bridesmaids had agreed to go and have a fun weekend together. Then today I got a text from one of them saying she felt she couldn't go because her grandmother had died a year ago on Sunday and she needed to be with her family. I totally understand this sentiment, I just wish she had told me before. She offered to pay her share in the weekend, but I just feel super awkward with her doing that. I don't want the other girls coming to have to pay more because she dropped out. What is the right thing to do here?
