Imagine 29 tables relatives : 16 tables friends

Man, I was like thinking in my heart.. Wouldn't I need to entertain a lot of people on my wedding night whom I dun really know? How to cover 10 tables on my family side and all other expenses with only 16 tables of friends??? How I wish the ratio is the other way round... No wonder I used to hear couples complain about how their wedding banquets turn out to be a family event & how they had to shake hands with so many "unknown" people on their day.

I know we have to respect & please our parents especially since we are the first in the family to get married. But I believe that there should be a good balance in the ratio in order for us to really enjoy our day by sharing our joy with people who are close to us. Not forgetting a good ratio can help to cover costs as well. Maybe a good ratio would be 25 tables relatives : 20 tables friends??? How to put across to our parents so that they can understand our concerns?
