Have a Wrap Party!
Set up wrapping paper, boxes, bags, tape, scissors, ribbon and all the rest of the paraphernalia in the center of the room.
Assign a different area of the room to each person; little kids may like to build "wrapping forts" by crouching behind chairs or sofas. Each area should have a flat surface like a floor or tabletop to facilitate those hospital corners!
Play Christmas music while everyone wraps their presents; come out of hiding for hot cider and popcorn when you're all finished.
