Heavy duty composite, interlocking tiles (30" by 42") are a stand-alone floor and need no additional framing or overlays.  The tiles create a safe, inviting integrated dance floor on uneven surfaces or areas where you wish to protect the grass or provide an improved surface.  Tiles quickly install and include a bevelled no trip edge around the entire boundary.  Dancefloor configurations are available up to 600ft2 and begin at a 10' x 11' configuration.  
 
Tiles are great for other high use party areas, for performers, at washrooms and other places visitors may gather and impact ground conditions.   See the dance floor configuration example to see suggestions of size calculation, and use of the space for your music-set up.
