My advice is to attend the wedding! Yes, it is difficult logistically and yes, it will be expensive, but he is your brother! I am still annoyed that 5 years ago I didnt attend a cousins wedding in Las Vegas because my daughter was 6 weeks old and I was nursing! I kept trying to think of an angle of how I could swing it! I do understand about not being able to stay at Sandals..is everyone else a "couple"? I guess I cant imagine them not making any exceptions! I just think you might regret not being at the wedding...my two cents! Good luck!
