I've actually read about a few couples doing this. I can see that the guests would probably preffer this option, but for me, i'm sticking with tradition. I think the build up to that special moment as you walk down the isle and see your FH face (hopefully smiling!) would be worth it. I've heard of grooms sending their fiancees little notes in the morning, or small gifts, or poems, which i think would be so special and totally add to the whole excitement and romance of the day. I've been hinting at FH how romantic it would be if a little note was delivered to me in the morning!I'll see if he catches on!
To keep guests busy, we have organised for a coach to pick them up after the ceremony and take them to the local village, which has a lovely old pub, and a few cafes etc. This way ppl can keep up the party spirit before the coach takes them to the reception venue. And having been a guest to weddings before, i've never found that "2 hour " wait a problem. By the time we get to where we are going and have a drink, its nearly time for the reception to begin anyway.
But i can see it both ways- but for me- i'll be keeping with tradition.
