My Fiance' and I are having our wedding (May 18, 2013) on a friends 20 acres and I am wondering what options do we have for bathrooms that guests use. It is a DIY wedding on a tight budget, in nothern Michigan. The wedding is not formal. There are about 200 guests and I am sure that my friends septic wont handle that many flushes. I am not sure if a porter potty is ok for guests at a wedding. Any suggestions on what I should do?
