OK so I am a bride on a budget, and my parents are helping SOME not ALL. Anyways the guest list is at about 425-450, yea crazy right? There are quite a few out of towners, but I am wondering for those who are having big weddings or have had big weddings, how many actually RSVP? Oh and if they do not RSVP they will be called. Any other tips to keep my budget where its at will help!!!
