Lay out plywood on a flat work space and make any cuts necessary to fit your desired dimension.
Apply vinyl flooring to the entire top surface of each piece of plywood using adhesive and the manufacturers instructions. Allow sufficient drying time before proceeding.
Arrange the plywood pieces in the desired configuration. Attached safety latches around the circumference of the plywood pieces at the edges where they meet. This ensures the pieces stay together while the dance floor is in use. The latches can be unhooked for dance floor dis-assembly and storage.
Attach the rope light brackets to the circumference of the dance floor along the outside edges of the plywood. Be sure to position the brackets so that guests won't trip over them.
Insert rope light into brackets and attach extension cord. Tape down extension cord to prevent being tripped over.
Hang lanterns over head in a manner that minimizes extension cord use. The lightweight rope can be extended overhead for added support. Secure tightly to prevent falling.
Extend cords to power source being sure to tape down loose cords.
