You may feel that you simply want to get married and want the most straightforward option. Southampton Register Office is a working office, without any facility for music, readings or photographs. There is limited space, therefore you would only be able to invite two adults to act as your witnesses.
Some couples choose this option, but if you feel that it is too limited to the administrative side, you may find that the Magnolia Room is a better choice for you. That way, you have the flexibility to invite more than just the two witnesses, and enjoy photographs with your guests.
