We're having a large party next Saturday for my FI's 40th birthday. Unfortunately our bathroom upstairs is STILL undergoing renovations and won't be ready. Our downstairs bathroom is also the laundry room, and I'm not gonna lie - it's pretty ugly in there.
My FI has suggested the idea of renting a porta potty. He says not a gross, icky one; a very clean, nice one. Our guests will all be seated outside so they would not have to leave from indoors to go outside to use it. I'm not sure how I feel about this. We did attend a BBQ a few weeks ago at a friend's house and they also had a porta potty set up in the driveway as they didn't want people in their house. Personally, I wasn't bothered by it and it was very clean. But I don't know how the general public feels about this. Is it tacky?
Also, the party is very casual - nothing fancy. What should I do?
