Line of dance refers to the counter clockwise motion of dancers around the floor. 'Line of dance’ must be adhered to when dancing traveling dances including: Waltz, Foxtrot, Tango, Quickstep, and Viennese Waltz, as well as Polka and country two-step. Latin and Swing dances are 'spot' or 'track' dances and have no line of dance. It is possible to dance more than one type of dance to the same song. In this case, 'spot' dancers take the center of the floor while traveling dancers move along the periphery in line of dance.
Getting on and off the floor: Exercise caution when getting on the dance floor, especially if the music has already started. It is the responsibility of incoming couples to make sure that they stay out of the way of the couples already dancing. Leave the floor quickly when you finish dancing. Move conversations off the dance floor.
Sharing the floor requires good dance floor management. Avoid getting too close to other couples. Be prepared to change the direction of your patterns to avoid congested areas. Match your speed to others. If you are moving more slowly keep to the center of the floor. When things go wrong always apologize. Generally it does not matter who is at fault.
