It's a popular choice for couples here to go off by themselves to the islands (Samoa, Fiji, Cook Islands etc)
and have that special time to themselves.
Later, if they can afford it, they have a big party for family and friends.
In my day it was even frowned on to go to a Registry Office. All 'respectable' people got married in church.
There were arguments about who should be invited, what to wear, what to eat, what to buy as gifts - it became a nightmare for very many brides and grooms.
Thank goodness our independent, modern children and grand-children are now thinking outside the rather stuffy box and doing it their own way.
