Tempted to make my reply by date even earlier!

I had a suprise party for my FH on Sunday, reply by a week beforehand. 1/2 the people waited until that exact day to reply and then 4 more did it after!!!! WTF! What is wrong with people???????????


Now I wonder if a month before the wedding is enough time?

when is your wedding date?
I made my rsvp date March 31st, do I really need 1.5 month in advance?
