I keep seeing ads for the bridal extravaganza, and a search through the Knot forums has not turned up any information. We already have the venue, caterer, photographer and music, but still need cake, groom/groomsmen clothing, transportation. Is going to one of these things worth it? I'm past the overwhelmed stage, so I don't think that will be a problem, but I just don't know if you already have the big things, is attending the extravanganza worth the time?
