The master of ceremonies vs the wedding planner
The master of ceremonies is the director of the wedding. But not the organiser. Although in practice, they are sometimes confused with a wedding planner. This is not surprising, as the two also have a lot in common. A wedding planner can then additionally function as master of ceremonies if you choose. But not vice versa.
What the master of ceremonies does: Supervise your wedding and make sure everything runs smoothly. He or she does not choose a venue (or photo location), does not send out invitations, does not make a script and does not hire anyone and does not make thank yous, at least not by himself. Of course, you can ask for help for all these things by mutual agreement, but in fact, the master of ceremonies is mainly there to monitor the course of events during the big day and has no organising role in the wedding.
The master of ceremonies is the point of contact for all questions, makes sure everything runs according to schedule and that things are ready to go that need to be ready (provided they have been delivered). In addition, the master of ceremonies also liaises with the suppliers, but you will have to provide them first.
What the wedding planner does: The wedding planner takes most of the tasks off your hands so that you don't have to arrange anything other than making the choices for what cake and snacks to have. A wedding planner organises your wedding from A to Z. This means scouting the venue, booking the catering, making a script, keeping suppliers informed and hiring the officiant. In addition, a wedding planner will also do all the styling of the venue itself so you don't have to worry about it.
