I found out that Kohler makes a luxury portable restroom that are available to rent. I had planned on renting those for my late summer reception at my parent's farm. Unfortunately, the local rental companies do not have any kind of portable restrooms to rent except for the ugly (smelly) kind you would find at a concert or little league field.
Is it considered in bad taste to have the regular porta-johns at the reception? Would it look better to open up my parent's home and my grandmother's home for guests to use (this would mean 2 restrooms for 200 people). Also, I could potentially have 5 restrooms available in the houses, but that would require people walking through a bedroom which did not seem appropriate at all.
*Note: we live on a farm and the tent is equal distances between my parent's home and my grandmother's home which is separated by a very large side yard, so both are easily accessed.
