How many'no's' did you recieve?

I am curious b/c we gaurenteed 120 and we want probobly no more than 120-130, 135 the most. Our list is about 175 but thats with 35 are guests, of which I dont think alot of people are going to bing guests its more of just proper etiquette that these individuals are invited with a guest.
So could I please get some feedback of number invited and actual number in attendance. Thanks.
