I evened it up! DH had his parents and best man, I had my parents, 2 bridesmaids and an usher. The Usher evened up the boys and girls (although I would have had him anyway - he wasn't in loads of official photos, but did sit at the top table).

The best photo I have is with me and DH, the best man and 2 bridesmaids around the cars in front of the castle. It looks like it should be in a magazine, it came out that well! I never thought it looked odd because of an odd number.
