Traditionally, all rooms are laid the same direction ... and Plan A would be traditional.
Like quilting, why feel you have to keep with tradition!
I too was worried about a bowling alley effect when I was restoring a 150 yo home with a long upper hallway. To solve that problem, we laid the strips on the bias ... plus it added interest to the other rooms.
I loved the look .... and we had many compliments when others saw the results.
