Visually or Economically?
Visually - to create a longer corridor: length ways; a wider corridor: width ways (also staggered cuts as opposed to stacked)
Economically - length ways as there are less loss /cuts - preferably staggered
For the bedrooms, you can either continue following the same direction of wood in the hallways, or use one "beam" as a visual threshold in the doorway to enable a change of direction in the bedrooms. This also is an economical solution as your bedrooms may require a change of direction...
