I do not agree with mayway, that it is foolish to spend thousands on a wedding. In Ireland, all aunts & uncles will expect to be invited to the wedding. Then, by the time you have paid for these, close friends & work colleagues, the wedding no.s will go to 150 people. Even if you cut back on food/drink etc, the wedding will still cost a lot, just to have the basic 3 or 4 course meal.
I find there is no happy medium in Ireland without offending people. If you just have a family wedding, you may only have 15 or 20 people. This is not really enough to have a 'party' atmosphere. Then if you have 60 or 80 people, you will probably have to leave out some relations/close friends etc, but you will have the band & 'party' atmosphere.
We had 80 people last year. It still cost about 14K for the whole wedding, excluding the honeymoon. We still offended some of my husbands relations, as we didn't ask them all. (He has a large extended family, whereas I have less relations). Even if you have 80, you still have to do things right re: food & drink.
