For what it's worth my wedding later this year should come in at about e14,000. That's for 130 guests. The meal will cost the lions share at about e10,000. Needless to say we are not having too many "extras" and are lucky enough to have a number of friends able to provide music, photography, flowers etc as gifts as they happen to work in those areas.
We're not compromising on anything important to us but we're not having vintage cars, favours, fairylight backdrops, seat covers etc. and to some people not having these is compromising.
