I've been told many different opinions on how many chairs/tables to get for 250 guest. Several people have told me to only rent 90% of my guest list so that I don't "over rent" on the number of chairs and waste money. They said that not everyone sits down at the same time and not everyone shows up. I am fine with under renting, but I don't want more to show up than planned or have that one in a million chances that everyone wants to sit down at the same time. Is there a event specialist out there that has a good idea of how many tables and chairs I should get that would help me on money AND provide enough seating? I just don't want a tent full of chairs if I don't have to have it that way...
