I recently called a wedding dance in a tiny church (the only building left standing after a plague killed off everyone in the village hundreds of years ago!).  We managed to clear a 3 x 5 yard area (but even that had dogs and sitting people intruding into the space!).
 
Fortunately it was a small wedding!
 
We had 20 people dancing in that space – very crowded – but they all had great fun!
 
No, we didn’t do any contras!
 
For a wedding, you use the space you have and make it fun.
 
Happy dancing,
John
