I was thinking along the same lines as you. My ceremony will be in Las Vegas and I didn't really want anyone else involved. I just really didn't want to bother anyone else with added expenses as far as buying a dress since they are already paying for their trip out to Vegas. However, after talking to my fiance one day, he said that he wanted his younger brother to be his BM which means that I will probably have my sister be my MOH. I think you can get away without having a bridal party and it be OK!
