I will be getting married next July, and we are having a beach themed wedding. Our ceremony will be on the beach, and our reception is in the building right behind the beach. We are paying for the wedding ourselves, so we are on a tight budget. The food for our reception is going to be buffet style, and we are contemplating if we should use paper plates and plastic silverware and cups. Is that tacky, or would it be ok since our reception and wedding are more casual feeling?
