Using Muvee I can knock one out in about 20min or less if I already flagged the images from Lightroom, export, drop in, arrange transitions, go. Animoto gives you legal music and is simple to bang them out too and you can tag it through Facebook/Youtube, etc. which is a plus for getting more eyes on them. I like to deliver a preview slideshow a few days out from the wedding they can share all over the place as it seems to keep the momentum going, a lot of brides are digital these days and want to twitter, facebook and email everything so its just one more tool to give them what they want, the way they want.
