hardwood-floor
See the above picture, it looks to me to decide layout of bedroom A,B,C and play room is pretty straight forward.
But I do not have any idea what is the better layout on the hallway should be?
I am also thinking if I should change direction in Bedroom A to avoid too much expansion at vertical direction.
Any advice is appreciated!
We only use Titebond III waterproof wood glue on Hardwood flooring. You can clean up excess with water before it cures. This stuff works great and allows some flexibility for expansion and contraction.
Since you can get to the floor from underneath, you can shore up the flooring by adding new joists between the existing ones. This will not be a FUN process, but the process is simple enough, just labor intensive.
First, add cross braces between each joist at each end, of the same dimensions as your existing joists. You'll want them to be snug fitting between each joist, and well supported with joist hangers.
Now, between each brace, halfway between each existing joist, hang new joists to fit between the cross braces you added. Before you permanently hang the joists, prop them up from beneath with 2x4 temporary posts to force the tops up to be level with the tops of the existing joists (pushing the flooring above back into shape), then secure them permanently in place with joist hangers.
Add blocking between the old and new joists as well, to ensure the new joists don't warp/twist.

I would divide the hallways into 3 areas and keep the areas approximately the same size. Put the direction of the wood with the longest wall to keep cuts to a minimum. In my mind this has the middle hallway start (reading left to right) with the angle change and end at the far side of bedroom C.
The change in direction from the hallway to the room would be transitioned at the door ways to make it as inconspicuous as possible.
Bedroom A should be fine. The hardwood manufacturers typically specify the maximum dimensions and that room doesn't look like it would exceed the standard recommendation but check the install specifications.
