Our ski house has an extra large bedroom which currently contains 4 beds. We would like to separate it into 2 more private sleeping areas but aren't sure of the best way. It has beautiful hardwood floors that we don't want to damage as someday we may want to put it back to large bedroom. It has 1 door - which leads you to the middle of the room.

Should we use furniture?? Or build a temporary wall??? Has anyone else had a similar project??
