The key to running a smooth run day is planning, particularly ensuring you have allocated enough time to do the things you want to do.
If you are getting married in a Church then typically the driver will aim to get you to the ceremony a 5 minutes before the scheduled ceremony start time. This is to ensure that you have time to exit the car gracefully, have photos taken and walk to the entrance. This is of course very flexible, if you have your own ideas about timings then this can be incorporated in to the itinerary.
Registry office weddings car slightly different, as usually you will not have met the registrar before your wedding date. It is part of the legal process for the registrar to meet you before the ceremony commences, so typically they recommend arriving 15 mins before the ceremony start time. This will vary from district to district, but don’t be concerned as the timings of the car itinerary can be clarified and amended closer to the date.
You will have pre-arranged with the reception venue what time you will need to arrive, this should be discussed with your photographer when you discuss the photography plan. The wedding car driver will be at your disposal and be ready to depart when you are ready.
