This week I checked on the size of the room, and it's 62' by 39'.  Here are a couple of possible lay outs.  All of these layouts will require borrowing about 6 6ft tables.   They also will require that we change the way we serve.  

 

  This is the lay out I prefer, it gives us a symmetrical hall with a nice center aisle.  There are 24 seats at  2 banks at 32 seats at the other 2 banks. I also have  an extra available on the end for extra child or general space.  We agreed on 125 for the feast.  With 12 at the head table this leaves 113 for the floor.
