The non-alcoholic weddings differ from the ones where alcohol is served. The wedding ceremony is usually extended by the reading of a special blessing (and acknowledgement) from the local bishop. Through this, the wedding reception does not only become exceptional because of the absence of alcohol and everything associated with alcohol, but it is also marked by other traditions and attractions. As toasts in Poland are almost by definition associated with alcohol, they are either removed entirely or replaced by table speeches, goat's milk toasts, songs in honor of the married couple and their parents and so on. As Polish wedding receptions are usually all night long events, usually the alcohol goes some way into keeping the guests awake and amused late at night. A non-alcoholic wedding differs significantly from this as dishes are served regularly, must be of comparable quality all the time, the orchestra has to play all the time and the party is enriched by various group dances (such as the polonaise, line dances, "travel dances", skill dances (zorba, mountain folk dances), games and competitions for the participants. Usually professional entertainers, who undertook special courses for non-alcoholic party entertainment ( "wodzirej") are employed during the reception to organize and run the entertainment program.
