When you see where this layout ran, you'll understand why my wife insisted it be temporary!
I ran it through the office, into and out of the master bedroom, through the hall and around the stairs and back into the office. It was very cool, and I am actually surprised I was allowed to keep it up for several days!
So, don't let a lack of space keep you from setting up a layout. Even if it is only for a day or two, it is FUN!
