I have been searching everywhere for dancefloor rental and the least expensive place I found is charging $18 per square and I'm thinking I need a 20x20 floor so that comes close to $600 since it will be on grass. I've been thinking about just making it myself, seems easy enough but I'm just worried about the whole set up and tear down process the day of. Anyone build their own dancefloor? What were the pros and cons?
