I've heard so many different avereage ratio's on how many people you invite versus how many people actually SHOW up? (I realize many factors do come into determnation, ie we are having our wedding about 45 minutes outside of town) Does anyone have a good idea what this ratio is usually like? For instance, I am inviting about 275 does that usually=200?? I am so scared EVERYONE will come and I'll end up paying an additional 6k or 150 will come and I wasted all this money on a giant wedding. HELP! Iam so confused on the "law of averages"? Thanks in advance.
