PARENTS ARE TURNING 50! NEED HELP PLEASE!

Iam trying to plan a surprise party for my parents. They both are turning 50 in November. Their birthdays are 1 week apart. I dont really have that much money, but was wondering if anyone knows of any Halls that I can rent? That arent too expensive I live in Patchogue, but if you know of anywhere in nassau, Iam open to Ideas. It will be around 50 people. All of my Aunts said they would cook food. Which will help a whole bunch! I just wish I could find a Hall to rent for Cheap.

aWWH. nO One??

We are waiting for an answer from my FIL. He is Chief of North Patchogue, but they have been really strict lately.
