I totally agree with xeney. You should not not do something just because it is conventional. (Bad grammar.) Do what feels good to you guys. DH bought be a great book that has some FANTASTIC suggestions: The Knot's Guide to Weddings in the Real World. This book was full of EVERYTHING wedding, and not just conventional type weddings. It also gives great advise, in terms of disagreements with in-laws, friends, and even your fiance. Let me know if you need any help or advise, I just did this a little over a year ago, I know what it is to fight with people to get what you want. Again, remember, it's you guys' day/wedding, not someone else's.
I'm totally going to pull out my wedding pictures now and I'm going to get all sappy. Poor DH.
