Help! This is the guest bedroom on the first floor.

First I think I need to go the long way as the room is a large rectangle (21' X 12') and wont that look odd butting up to the hall going the same way? Second, I didn't realize there would be such a height difference after I took the carpet out. Is my only choice to go with what I have in the hall? Its really dated and I really don't want to fight with real hard wood, just want something quick that clicks together...

Any recommendations on how to proceed would be appreciated!!
