One thing I would like to add to that is with that
many people expected, things can become very chaotic,
very quickly. In order to control the potential for
chaos, we really need to be very well organized. We
are really going to need some help from the singles
(why, you ask? Because although a lot of the parents
are assisting with the banquet, we all have kids that
are going to have needs and it can get hectic when
tugged on one side by a child and the other by the
stress of volunteering), so we need the singles to go
above and beyond the call of duty.

Second, we need to decide how we want to handle
serving the food. With that many people, it will take
a lot to control the amount of people who will get in
line for the food. I'm assuming that we will have it
as a buffet line but might I suggest one of 2 options:
 1) Have the initial dish served to each person
sitting so we don't have tons of people going for the
food. Sit down style. After the first round of food
is served, people can get up to help themselves for
2nds. This helps control the amount of people and the
amount of food given. 2)Have people man each item of
food that we are serving so we can control what is
served. We can call out the tables that we want to go
into line to be served, guests should be first, etc.
I think the serving of the food will be the most
hectic.

I will volunteer to be the talking waiter. Who's coming with me.
