What was the biggest headache for you during wedding planning? Mines were several things:
My FMIL telling me her friends sent the RSVP back and they said that they don't understand why their RSVP said one when they are bringing their grown daughter, daughter husband, two son (me and FH do not know the extra people btw)
The seating chart. its getting to the point where im about to say except for immediate family, every man for themselves..lol
