Ok backstory... we just got engaged on Easter Sunday, and on Monday afternoon he had already asked 5 guys to be gm's! We're not getting married until May 2011 and haven't acutally booked anything yet and, after reading posts here, I wanted to wait to ask my bm's until later this summer.
The issue of "even sides" came up because one of his friends is in the armed forces and obviously can't predict where he'll be next year, so we're not sure if there will be 4 or 5 on his side. I am ok with just asking 4 girls and then possibly having two guys escort one girl but FI and my parents (who are paying) are pretty insistant that sides match. How can I convince them it's not the end of the world? I would love to compromise but can't think of anything that doesn't involve back-ups (which I think is so rude!) TIA for any advice
