So, we are having our dinner reception in a private room of a restaurant. Everyone will be there before us since we'll be doing a few pictures after the ceremony. We aren't having a dj or dancing, only an accoustic guitarist playing background music throughout cocktail hour and dinner. Should we have some kind of introduction from our DOC? Or just walk in casually during cocktail hour and start to mingle? Also, should we introduce the wedding party, since they won't be introduced either if we aren't, or just let them introduce themselves during toasts?
