Create a Trade Show Booth layout

Attached is the diagram of the hall we are renting for a sale this fall. We have the three rooms of this hall. The file named Merritt Hall 1 is the diagram I would like altered. The File named Merritt Hall 2 is an example of the alteration that needs to happen but there are errors. The File named Ancaster Layout is the exact booth layout with numbers that I want replicated into the File Merritt Hall 1. This is a much larger document as I am using Grapic paper
