This is my first time in a forum, so bear with me 
My friend, who got engaged around the same time as I did, asked me to be to be a BM. I accepted and I've been helping her plan her wedding in addition to my own. She has moved the date and location three times now, deciding on TN when everyone lives in either TX or LA. Just yesterday she told me that we were all going to stay in a cabin together the days leading up to the wedding and that she wanted a half of the costs (the total cost to rent the cabin including the damage deposit split equally between the bridal party) from everyone to reserve the cabin by the beginning of January. She also told us that she is using the cabin as her reception venue. I feel like she is using us to help pay for her reception venue. Is she asking too much of her bridesmaids to pay for this cabin and to drive 15 hours to the wedding? Sorry for the novel. Thanks!
