What is the traditional order that families are seated prior to the ceremony beginning?
Here's who all will be walking out:
My mom/brother (his GF will be sitting down already, and my stepdad is escorting me)
FI's sister and her 2 boys
FI's mom and stepdad
FI's dad and his GF
Also when should FI and his best man come out? Before or after the families are seated?
